摘要:

目的:了解洱海水硫化物及六价铬含量。方法:采集洱海20个点的水样对硫化物及六价铬的含量进行检测,分别采用
亚甲蓝分光光度法,二苯碳酰二肼分光光度法进行测定。结果按照《地表水环境质量标准进行评价》。结果:硫化物、六价铬
合格率为100%。结论:硫化物、六价铬均达到GB 3838-2002《地表水环境质量标准》的一类水质。

关键词: 硫化物, 六价铬, 检测, 洱海水

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
