有机粘土对染色废水吸附脱色研究

Adsorbing and Decolourizing Property of Organic Clay for Wastewater from Dyeing Process

用十六烷基胺对粘土进行改性处理制得有机粘土吸附剂,考察该吸附剂对废水的吸附脱色效果。实验室研究结果表明:有机粘土在废水脱色中优于无机粘土,但比活性炭的吸附能力稍差,可以部分代替活性炭。

Cetylamine was used for modification treatment of clay, with organic clay adsorbent obtained. Results of adsorption and decolorization with the said adsorbent were evaluated. The laboratory test showed that organic clay was better than inorganic clay for the decolorization of wastewater but its adsorptivity was slightly poorer than that of active carbon and, therefore, it may be used to partially substitute for active carbon.
