摘要

介绍了几丁质胺化对RB5和RY84染料吸附效果的影响。对甲壳素和胺化改性甲壳素，测定了活性基团和分子量不同的活性染料活性黑5 (RB5)和活性黄84 (RY84)的最佳吸附pH和最大吸附量。采用Langmuir、Langmuir 2和Freundlich三种吸附模型来描述实验数据。两种染料对胺化甲壳素的吸附量最高:RB5为386.53 mg/g, RY84为261.56 mg/g。在未改性甲壳素上吸附时，吸附量较低，可达235.65 mg/g.d.m。RB5和208.88 mg/g.d.m。RY84。氨基化改性甲壳素对染料吸附量有很大的影响。RB5的吸附量提高1.6倍，RY84的吸附量提高1.25倍。

THE INFLUENCE OF CHITIN AMINATION ON THE EFFECTIVENESS OF RB5 AND RY84 DYE SORPTION

This article presents the influence of chitin amination on the effectiveness of RB5 and RY84 dye sorption. For chitin and chitin modified by amination, the optimal pH of sorption and the maximum sorption capacity were determined in relation to two reactive dyes: Reactive Black 5 (RB5) and Reactive Yellow 84 (RY84), differing in the active group and molecular weight. Three sorption models were used to describe the experimental data: Langmuir, Langmuir 2 and Freundlich. The highest sorption capacity was obtained for aminated chitin for both tested dyes: 386.53 mg/g for RB5 and 261.56 mg/g for RY84. In the case of sorption on unmodified chitin, the sorption capacities were lower: up to 235.65 mg/g.d.m. for RB5 and 208.88 mg/g.d.m. for RY84. The modification of chitin by amination has a beneficial effect on the amount of dye adsorbed in the process. The adsorptive capacity increased by 1.6-times in the case of RB5 and 1.25-times in case of RY84.
