Description:
This limited project was conducted to determine the usefulness of the D.C. argon plasma for the analysis of wastewater. Seven priority pollutant elements, arsenic (As), beryllium (Be), cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb), and thallium (Tl), were selected for use in this project. A discussion on the linearity, instrumental detection limit, and stray light effects for each element is included. The report contains precision and accuracy data on a mixed domestic-industrial effluent spiked at three concentrations. The effect of varying the concentration of the matrix buffer and the need for matrix matching of the standard to sample are also discussed.
