Simultaneous determination of 10 elements in wastewater, plasma, and bovine liver by inductively coupled plasma emission spectrometry with electrothermal atomization
A sample introduction system is described to electrothermally atomize microsamples of liquids and solids for multiple element assays by inductively coupled argon plasma emission spectrometry. Five- to ten-microliter liquid samples were transferred to a groove in the carbon rod atomizer, dried, and atomized with the analytes carried into the plasma torch in a flow of argon. Solid samples (0.5 mg) were weighed into a graphite microboat which was placed on the carbon rod and assayed in like manner. No ashing or sample preparation was necessary. Recoveries from wastewater and blood plasma were between 60% and 136%. Results for the samples of NBS bovine liver (1577) were compared to the certified values. Calcium, cadmium, copper, iron, potassium, magnesium, sodium, phosphorus, lead, and zinc were determined in wastewater, human blood plasma, and NBS bovine liver (1577). 7 references, 2 figures, 2 tables.
