摘　　要：将废弃猪革制备成一种廉价的吸附剂,研究其对水体中Cr(Ⅵ)的吸附性能。结果表明:在粒径为2mm、pH值为2左右、初始浓度5mg/L、用量为0.8g、温度35℃、时间为3h条件下,对六价铬的去除率达到97.19%。利用废弃猪革屑处理低浓度含铬废水,具有很高的应用价值。The abandoned pig leather was used as a low - cost absorbent, and its adsorption to Cr（ Ⅵ） in aqueous solution were investigated. The experimental results indicate that under the following conditions, the adsorption rate of the abandoned pig leather to Cr （ Ⅵ） is 97. 19% ： the particle size is 2mm, the pH value is around 2, the initial concentration of Cr （ Ⅵ ） in the solution is 5mg/L,the dosage of adsorbent is 0. 8g, the sorption temperature is 35℃ ,the sorption time is 3 hours. The abandoned pig leather absorbent has a good treatment effect for low concentrations Cr（ Ⅵ ） in wastewater, which has a high application value in the treatment of wastewater.
