| Abstract: | In this paper, the preparatory treatment for determination of Cr6+ in ground water or industrial effluents by the method of spectrophotometry has been improved. The feature of the improvement is accurate, quick, simple and economical. It can be satisfied for environmental monitoring. The results from measuremet of the method with the improvement is in accord with ones from measurement in the reference 1. |
