Chemical Speciation Approach to Evaluate Water Quality Problems in the Blackbird Mining Area, Idaho

摘要

The research studied the effects of the contaminated sediments on the water quality of the creeks surrounding the Blackbird Mining area. Experiments were conducted to evaluate the leaching characteristics of arsenic species, As(III) and As(V), and other trace metals from sediments collected. A solvent extraction method was developed for the separation of arsenic and antimony species in natural waters using pyrrolidinecarbodithioate (PCDT) as a chelating agent.
