羧基化改性纤维素及其对苯丙胺的吸附性能研究
Carboxylated Modified Cellulose and Its Adsorption Properties for Amphetamine
摘要
Abstract
In this study,cellulose was used as the raw material,and it was esterified by polyacidic anhydride to prepare the carboxylated mod-ified cellulose material(Cell-COOH).The preparation conditions of Cell-COOH were optimized through one-factor experiment,the structure of Cell-COOH was characterized,and its adsorption properties and behaviors were investigated.The results showed that the equilibrium ad-sorption capacity of Cell-COOH on 20 mg/L amphetamine solution was 34.59 mg/g under the conditions of cellulose to homophthalic anhy-dride mass ratio of 1∶3,reaction temperature of 115 ℃,and reaction time of 1.5 h.The adsorption behavior of Cell-COOH towards amphet-amine was in accordance with the Langmuir isothermal model and the pseudo-second kinetic model,which was mainly single-layer-chemisorp-tion,and the adsorption process was a self-motivated exothermic reaction.The adsorption capacity of Cell-COOH towards amphetamine was 92.64％of first adsorption after 7 cycles of adsorption-desorption experiments,showing a good stability and reusability.关键词
