【Abstract】 An indirect AAS determination of carbon disulfide in waste water is described in this paper. In an alkaline medium, CS 2 reacts with diethylamine to form DDTC which is further reacted with Ag + to form AgDDTC. The trace amount of CS 2 is determined indirectly by the determination of Ag(Ⅰ) by AAS. A linear relationship holds in the range of 2~30μg of CS 2 per ml. and the limit of detection for CS 2 is 1.02μg·ml -1 . The presence of H 2S and Cu(Ⅱ) do not interfere with the determination.更多还原
