Analysis of Wastewater for Metals using ICP-OES
IntroductionThe Analysis of Wastewater for trace metal contamination is an important step in ensuring human and environmental health. Wastewater is regulated differently in different countries, but the goal is to minimize the pollution introduced into natural waterways. In the , the Environmental Protection Agency (EPA), in conjunction with the states, negotiates a discharge permit through the National Pollutant Discharge Elimination System (NPDES) which takes into account the federal guidelines for the industrial category (40 CFR, Parts 405-471)1 and the sensitivity of the waterway receiving the discharge. Therefore, Wastewater may need to be measured for a variety of Metals at different concentrations, in different Wastewater variety of inorganic techniques can be used to measure trace elements in waste water including atomic absorption spectroscopy (AAS), inductively coupled plasma optical emission spectroscopy ( ICP-OES ) and ICP mass spectrometry (ICP-MS).
