#iitutor #Chemistry #ChemicalEarth https://www.iitutor.com The process of finding out what is present in a particular chemical sample is called chemical analysis. Chemical analysis can be qualitative or quantitative. Qualitative analysis involves determining what substances are present in a sample. Quantitative analysis is about determining how much of each substance is present in a sample. Two common methods of quantitative analysis are gravimetric analysis and volumetric analysis. Volumetric analysis is concerned with the measurement of solution volumes. Gravimetric analysis is a method of analysis that involves the measurement of masses. Gravimetric Analysis. This involves the accurate measurement of masses. This is done often in the pharmaceutical, food and mining industries. Often procedures will involve the weighing of precipitates to find product mass, measurement of combustion by products and in the study of empirical formulae. Percentage composition. The percentage composition of a chemical compound specifies the percentage by mass of each of the different elements present in the compound. For example, water consists of 11.1 per cent hydrogen and 88.9 per cent oxygen by mass. A 100 g sample of water therefore contains 11.1 g of hydrogen and 88.9 g of oxygen. The percentage composition of a compound can be determined experimentally using gravimetric analysis. For example, information about chemical composition can be determined by decomposing the compound and weighing one or more of the products.

#iitutor #Chemistry #ChemicalMonitoringAndManagement https://www.iitutor.com AAS is developed in the 1950s by Sir Alan Walsh and his team at CSIRO. Instrumental techniques can detect the concentrations of ions or molecules at very low levels and with great accuracy. It is used to detect and measure the concentration of metals in a sample. Atomic absorption spectroscopy (AAS) is a sensitive technique that can measure the concentrations down to parts per billion, ppb) of metals in various materials. Principle Different metals vaporised in a flame absorb light of specific frequencies. Hollow cathode lamps emit light of specific frequencies for each metal that forms the cathode. This light is absorbed by atoms of the element to be measured. To measure the concentration of a specific metal in a sample, a hollow cathode lamp specific to -'pat metal is used (e.g. if copper is to be eared in a sample, then a hollow copper cathode lamp is used). A series of diluted standard solutions are separately analysed by spraying them into the flame of the burner. Light from the hollow cathode lamp is passed through the flame and is absorbed by the hot atoms in the flame. The degree of light absorption is proportional to the concentration of the metal in the flame. Photomultiplier tubes detect the intensity of light transmitted for each sample and compare this with a control that contains no atoms of that element. The degree of absorption of light (absorbance, A) is then determined automatically. A solution of the sample to be analysed is now sprayed into the flame of the burner and the intensity of light absorbed determined. The concentration of metal in the sample can be determined from a calibration graph of the diluted standards. A sample, thought to contain a metal ion, is heated in a flame. The species in the sample are converted into bases. If light of a frequency known to be absorbed by this metal ion passes from the light source through the heated sample, the ion in the sample will absorb some of this light. The proportion of the light energy absorbed by the sample (the absorbance) is proportional to the concentration of the metal ion in the sample. The instrument must be calibrated for each metal ion being tested, and a separate light source must be used for each metal ion. Uses of atomic absorption spectroscopy Micronutrients and trace elements Before the development of AAS in the 1950s, it was difficult for scientists to determine the levels of micronutrients in plants and animals. Their standard chemical techniques were not sensitive enough to measure concentrations in the range 1-100 ppm. Atomic absorption spectroscopy is an important technique in the determination of the levels of these micronutrients or essential trace elements in the soil and in living things. A deficiency of essential trace elements in our diets leads to severe health problems. Blood and urine tests can quickly reveal the concentrations of these elements in our bodies. There are about 15 trace elements that are essential for animal life. These include: Mn, Co, Cu, Zn, Mo, W and I. Zinc, for example, is needed for the metabolism of amino acids and in energy production. Manganese is required for blood clotting and is also involved in carbohydrate and fat metabolism, while copper is needed for the production of enzymes involved in oxidation reactions. Heavy metals Atomic absorption spectroscopy is also very useful in monitoring the concentration of heavy metals in polluted water and soil as well as their levels in food. Metals such as mercury, lead and cadmium are toxic to the body and their presence in the water or food we consume will lead to serious health problems. Seafoods such as oysters are filter feeders and they tend to bioaccumulate (i.e. concentrate) heavy metals in their flesh. Higher order consumers in the ocean's food chain also accumulate heavy metals. Fish, for example, cannot contain more than 0.5 ppm of mercury. Consequently, an analysis of such foods will establish whether it is fit to consume. The analysis is also a first indication of the pollution of the waterway.

We present an overview of recent advances in chemical production scheduling, including a general framework, new modeling and solution methods, and some concepts for the online solution of scheduling problems. First, we develop a framework for the description of scheduling problems in the chemical industries. While building upon ideas used in discrete manufacturing, the proposed framework accounts for features such as material handling restrictions which make chemical production environments different. Second, we present a classification of the various modeling approaches that have been presented in the process systems engineering (PSE) literature and offer some critical insights. Third, we briefly review a series of mixed-integer programming (MIP) models developed to address limitations of existing approaches and present an overview of two solution methods that lead to order-of-magnitude speedups, namely, a constraint propagation algorithm for the calculation of parameters used to generate tightening constraints, and a series of reformulations. Finally, we close with some thoughts on the treatment of scheduling as an online problem with desired closed-loop properties. Biography: Christos was born in Athens, Greece. He obtained a Diploma in Chemical Engineering at the National Technical University of Athens, an MSc in Operational Research from the London School of Economics (London, UK), and his PhD from Carnegie Mellon University.

#iitutor #Chemistry #ChemicalEarth https://www.iitutor.com/ Aim: To determine the composition of a sand, water and salt mixtures by gravimetric analysis. Method: The supplied sample tube contains a mixture of sand, salt and a little water to form a damp mass. Weight the tube and contents and record the mass (m1). Using wash bottle and stirring rod, transfer the contents of the tube to a pre-weight filter paper (m3) supported in a filter ring over a large pre-weighted evaporating (m2). Rinse the tube and wash the sand that collects in the filter. Remove the filter paper and place on a clean watch glass. Dry to constant weight in a drying oven. Record the mass of the dried filter paper + sand (m4). Partially evaporate the salt water slowly on a hot plate and complete the evaporation in a drying oven to avoid splattering of salt. Wight the dry basin and salt (m5). Wight the clean, dry sample tube (m6). A sample of a copper alloy to be used for coins and medals was analysed to determine whether its copper content was in the acceptable range of 90-92%. A 5.000 g sample of the alloy was dissolved in concentrated nitric acid and the solution that formed was diluted and the copper extracted as pure copper metal by electroplating it onto a pre-weighed platinum electrode. Use the collected data below to determine whether the alloy contained an acceptable amount of copper. Accuracy: Improved by: Ensuring that all materials are quantitatively transferred from the sample tube to the filter paper and evaporating basin. The sand on the filter must be thoroughly washed to remove any salt. Splattering of salt during evaporation must not occur and a weighted clock glass may be needed to prevent loss of mass. Drying samples to constant weight is important. A pre-weighted filtering crucible will be more accurate than a filter paper as filter papers are absorbent.
