Abstract
The application of anodic stripping voltammetry (ASV) to the determination of several trace metals in coal ash was studied.
An ashing and ash digestion method was developed which limited the total salt and acid concentration of the analyte solutions, a necessary step for routine analysis. The simultaneous determination of cadmium, copper, lead, and zinc in eight Pennsylvania State University Coal Bank Samples and in the National Bureau of Standards SRM 1632a coal sample were made. Chromium was separated from the prepared coal ash solutions and determined independently in the form of chromate(VI).
All values determined by ASV methods were in good agreement with those determined by auomic absorption spectrophotometry. There was also good agreement between the anodic stripping voltammetry values and those reported for the NBS 1632a coal sample, and most of the values reported for the Pennsylvania State University coal samples.
