Determining arsenic and selenium in sewer effluent with atomic absorption spectrophotometry and a hydride generator
Technical Report
·
OSTI ID:6548174
A hydride generator was used with the described atomic absorption spectrophotometric method to determine the arsenic and selenium in sewer effluent. For analysis, the optimum concentration of hydrochloric acid was found to be 0.9N for arsenic and 3N for selenium. Studies were also conducted on the time required to collect the generated hydride and on the interference of nitric and perchloric acids on sensitivity.
