摘　　要：用改性PAC对含Cr6+废水进行处理,研究了在不同条件下Cr6+的去除率。结果表明,在pH>12或pH<2、改性PAC的投加量为0.9 mg.L-1的条件下,Cr6+去除率可达94%以上。外加磁场后,当磁化时间大于30 min、磁场强度大于500 mT时,去除效果明显提高。The magnetic-assisted treatment of wastewater containing Cr^6＋ by modified PAC has been studied. The results showed that removal rate of Cr^6＋ was over 94% when pH value was 〉12 or〈2 and the addition amount of flocculant was 0.9 mg . L^-1. Under the magnetic field,when magnetization time was over 30 min and intensity of magnetic field was over 500 mT,the removal rate of Cr^6＋ increased seriously.
