碳基高价银分子晶体电池处理铬污染源水试验研究

以扬州第四水厂的沉淀后出水作为原水，模拟突发铬污染，通过投加碳基高价银分子晶体电池进行应急处理的实验研究。实验结果表明：碳基高价银分子晶体电池对铬的吸附在30min内能达到88.2％的吸附容量；碳基高价银分子晶体电池对铬的吸附符合Langmuir吸附模式；溶液pH值大于5时，吸附几乎为0；对进水质量浓度小于0．75mg／L的铬污染水样，接触时间5min以内便能使出水中铬的质量浓度降到生活饮用水标准的限值0．05mg／L。

Experimental Study on Treatment of Chromium Contaminated Water by Carbon-based High-valence Silver Molecular Crystal Cell

Emergency treatment experiments of simulating chromium contaminated water was studied by adding carbon-based high-valence silver molecular crystal cell,which raw water was effluent after precipitation of the fourth water plant in Yangzhou.The results show that the adsorption capacity of chromium by carbon-based high-valence silver molecular crystal cell in 30 min can reach 88.2% which meets Langmuir adsorption model.When solution pH is greater than 5,adsorption capacity is almost zero.When the concentration...
