Analysis of Mercury in Wastewater by Microwave Digestion Followed by Inductively Coupled Plasma Mass Spectrometry: Comparison with U.S. Environmental Protection Agency Methods Approved in 40 CFR 136.3
Abstract:As a cost-saving measure, the use of an existing microwave digestion system and inductively coupled plasma mass spectrometry instrument was investigated for the analysis of mercury in domestic wastewater, industry effluent, stormwater, and other aqueous matrices analyzed under the City of Portland's (Oregon) various National Pollutant Discharge Elimination System (NPDES) permits. A formal alternate test procedure application (ATP) study was undertaken to add total mercury to the analyte list for the CEM microwave digestion method (
During the study period and while waiting for approval, all NPDES mercury samples were sent to a contract laboratory for analysis by U.S. EPA method 1631E (
