Detection and Analysis of the Content of Sulfide and Six-Chromium in the Water of Erhai Lake

Abstract

Abstract:

Objective: To learn the content of sulfide and six-chromium in the water of Erhai Lake. Methods: Water samples from 20
sampling points in Erhai Lake were collected. Methylene blue spectrophotometric was applied to test the content of sulfide; and
diphenylcarbazide spectrophotometric was performed to test the six- chromium. The result was evaluated by "Surface Water
Environmental Quality Standard". Results: The percentage of the pass were 100% in sulfide and six-chromium. Conclusion: Sulfide
and six- chromium were consistent with a water reached GB 3838-2002《Surface Water Quality Standards》

Key words: sulfide, six-chromium, detect, the water of Erhai Lake

CLC Number:

R123.1
