摘要： 采用氨基硅烷偶联剂KH550对伊利石原矿进行改性，研究了改性伊利石对某企业含铜废水的处理效果。结果表明：在50 mL Cu²⁺质量浓度为194.65 mg/L的含铜废水中投加1.7 g的改性伊利石，Cu²⁺去除率可达到99.5%，废水中剩余Cu²⁺质量浓度为0.97 mg/L，达到《铜、钴、镍工业污染源排放标准》（GB 25467-2010）的铜排放标准要求。改性伊利石对Cu²⁺的吸附过程以化学吸附为主。

Abstract: Using amino-silane coupling agent KH550 for the modification of illite crude ore,the treatment effect of modified illite on the wastewater containing Cu²⁺ has been researched. The results show that the removing rate of Cu²⁺ can reach 99.5%,when 1.7 g of modified illite is added to 50 mL of wastewater containing Cu²⁺ whose mass concentration is 194.65 mg/L. The residual Cu²⁺ mass concentration is 0.97 mg/L,achieving the "Discharge Standard of Industrial Pollutants for Copper,Cobalt,Nickel"(GB 25467-2010). The adsorption process of Cu²⁺ by modified illite is mainly chemical adsorption.

Key words: amino-silane coupling agent KH550, modified illite, wastewater containing Cu²⁺
