摘要/Abstract

摘要： 考察了改性前后活性炭表面基团、孔径变化以及对百草枯吸附能力的影响,采用Boehm滴定法和液态氮吸附对活性炭进行了表征。结果表明,随着硝酸处理时间的延长,YK系列活性炭的吸附主要以介孔和酸性官能团共同影响吸附效果,从而增加椰壳活性炭对百草枯的吸附能力。用Langmuir和Freundlich等温模型拟合,拟合数据较为符合Langmuir模型,吸附过程更符合准一级动力学模型。通过Dubbininin-Redushkevuch模型计算,表明活性碳吸附百草枯是一种化学过程,Van't Hoff模型表明百草枯的吸附是以一种自发可行的方式进行,椰壳活性炭被证明是一种从水溶液中吸附百草枯的有效材料。

Abstract: The changes of surface groups and pore size of activated carbon before and after modification and the effects on the adsorption capacity of paraquat were investigated. The activated carbon was characterized by Boehm titration and liquid nitrogen adsorption. The results showed that with the prolongation of nitric acid treatment time, the adsorption effect of YK series activated carbon was mainly influenced by mesoporous and acidic functional groups, thus increasing the adsorption capacity of coconut shell activated carbon to paraquat. Langmuir and Freundlich isothermal models were used to fit the fitted data. The fitted data were more consistent with Langmuir model and adsorption process accords with the quasi-first order kinetic model. Through Dubbininin - Redushkevuch model calculation, which indicated that active carbon adsorption paraquat was a chemical process, Van’t Hoff model showed that paraquat adsorption was a spontaneous feasible manner, coconut shell activated carbon was proved to be a kind of effective adsorption paraquat materials from the aqueous solution.
