摘要 以脱硅稻壳残渣为原料制备活性炭,探讨了其对废水中靛蓝的吸附性能,考察了吸附时间、吸附剂用量和pH值等因素对吸附效果的影响.结果表明,靛蓝吸附过程符合Koble-Corrigan吸附等温模型,吸附过程是自发的吸热过程.利用准一级动力学方程、准二级动力学方程及粒子内扩散方程检验了吸附过程的动力学特性,活性炭吸附靛蓝的吸附动力学行为可以用准二级动力学模型描述,表明该吸附属于化学吸附.298 K时,活性炭吸附靛蓝的最大吸附量为1.05 mmol·g-1,对靛蓝有良好的吸附作用,可以作为染料废水处理吸附剂. The activated carbon derived from the residue of desilicication rice husk was used as the potential adsorbent for the adsorption of indigo from the wastewater. Experiments were conducted to study the factors affecting the adsorption process such as the contact time the dosage of adsorbent and the initial pH. The equilibrium data agreed well with the Koble-Corrigan isotherm model. The adsorption process was spontaneous and endothermic process. The pseudo-first order model, pseudo-second order model and intraparticle model were used to describe the kinetic data. The dynamic data fitted the pseudo-second order model well which suggested that the adsorption might be a chemisorption process. According to the evaluation with the Langmuir equation the maximum adsorption capacities of indigo dye onto activated carbon was 1.05 mmol · g^-1. It shows that the activated carbon derived from the residue of desilicication rice husk has a good adsorption performance for the indigo dye and can be used as adsorbent to treat the wastewater with high quality.
