Abstract

Because of the toxicity property of chromium in the water, it is important for the water environment to monitor the trace chromium with a kind of simple and sensitive method. Spectrophotometry of CAS and CTMAB is adopted to determine chromium in the Fu-yang river. The results indicates that the detected limit of this method is 0.0005 ug/mL, the mark-on recovery ranged from 87.7% to 97.0% and relative standard deviation is 5.0%. In addition, several problems needing attention about experiment process are posed in this paper.
