摘　　要：采用麦壳为生物吸附剂,研究其对十二烷基苯磺酸钠（SDBS）的吸附作用。结果表明：麦壳能迅速有效地吸附SDBS,40min基本达到平衡;增大SDBS的初始浓度,吸附量随之增大;增加吸附剂的用量,吸附量随之减小;SDBS溶液pH值在5~8范围内,吸附效果较好;升高温度对吸附有利;麦壳对SDBS的吸附符合Langmuir等温模型。Using wheat shell as biological adsorbent,the adsorption effect of sodium dodecylbenzene sulfonate（SDBS）was studied.Results showed that,wheat shell could effectively adsorb SDBS rapidly,it took about 40 min to reach the equilibrium;the adsorption quantity increased when increasing the initial concentration of SDBS,while decreased when increasing the dosage of adsorbent;good adsorption effect was obtained when the pH value of SDBS solution was in the range of 5~8;increasing temperature was good for the adsorption.The adsorption behavior of wheat shell to SDBS was consistent with Langmuir model.
