摘　　要：本文将木质素进行烷基化改性,利用产物吸附水中的Cr(Ⅵ),并对影响吸附效果的因素进行了研究。表征结果表明,木质素结构烷基含量增加。吸附结果表明,当体系p H为2,室温下改性木质素对Cr(Ⅵ)的吸附量可达到8.66mg/g,随温度而变化的吸附量说明化学吸附主导地位。This article is alkylated lignin modified by adsorption of the product of Cr （Ⅵ）, and factors affecting the adsorption was studied. The characterization results show that increasing alkyl content of lignin structure;adsorption results showed that when the pH was 2, at room temperature for modified lignin for Cr （Ⅵ） adsorption capacity could reach 8.66mg/g, adsorption capacity varies with temperature description dominant chemical adsorption.
