摘　　要：用高岭土吸附去除废水中的苯胺,研究了不同搅拌时间、pH、投加量等条件下的吸附效果。结果表明,室温条件下,pH=8.0,搅拌时间2 h,静置1 h,100℃烘干高岭土投加量为0.5 g,苯胺浓度为40 mg/L时,对苯胺的去除率可达79.82%。Adsorption with Kaokin,aniline removal from wastewater. Study on the adsorption effect under the condition of different mixing time, pH and dosing amount, etc. Results show that： at room temperature, pH = 8.0, stirring time of 2 h, allowed to stand for 1 h at 100℃, drying Kaolin dosage to 0.5 g and ani- line concentration of 40 mg/L,aniline removal rate up to 79.82%.
