摘　　要：以水性油墨废水絮凝污泥为原料、采用一步炭化活化法制备了吸附剂,并将其用于阳离子蓝X-GRRL溶液(300 mg/L)的吸附处理。考察了吸附剂投加量、吸附时间、吸附温度和吸附pH对吸附效果的影响,并对吸附动力学进行了探讨。结果表明:所制得吸附剂的总孔体积为0.5 cm^3/g,平均孔径为7.12 nm;在吸附剂投加量0.6g/L、吸附时间420 min、吸附温度25℃、吸附pH 5.4的条件下,吸附量高达486.21 mg/g,脱色率达97.24%;该吸附剂对于阳离子蓝X-GRRL的吸附过程可用准二级动力学模型和颗粒内扩散效应模型很好地描述。The adsorbent was prepared by one-step carbonization and activation method from flocculation sludge of water-based ink wastewater and used for adsorption treatment of cationic blue X-GRRL solution (300 mg/L). The effects of adsorbent addition amount,adsorption time,adsorption temperature and adsorption pH were investigated, and the adsorption kinetics was discussed. The results showed that:The total pore volume and average pore diameter of the prepared adsorbent were 0.5 cm^3 /g and 7.12 nm respectively;The adsorption capacity of the adsorbent was 486.21 mg/g and the decolorization rate was 97.24%,when the adsorbent addition amount was 0.6 g/L,the adsorption time was 420 min,the adsorption temperature was 25 ℃ and the adsorption pH was 5.4;The adsorption process of cationic blue X-GRRL on the adsorbent could be well described by pseudo-second-order kinetic model and intraparticle diffusion effect model.
