摘　　要：用阳离子纤维吸附水溶液中的阴离子活性染料X-BR,从吸附条件和吸附动力学2方面研究了阳离子纤维对阴离子染料的吸附情况,比较了不同条件下阳离子纤维的吸附及解吸性能。结果表明,在阳离子纤维浸入含染料水溶液中的吸附与解吸的研究中,染料溶液初始含量越大,吸附速率常数越大,吸附符合伪2级动力学模型;染料水溶液中含有电解质如NaCl、Na2SO4对吸附过程有一定影响;随着阳离子纤维吸附量的增加,NaOH溶液含量增加,解吸率随之增加。The cationic cellulose was used to adsorb ionic dye X-BR. The adsorption behavior was investigated from adsorption condition and kinetics. The results showed that adsorption velocity of cationic cellulose increased with increase of dye initial concentration, and its adsorption behavior agree with second grade kinetics model. Some salts, such as NaCl, Na2SO4 could affect the adsorption velocity. The desorption velocity of cationic cellulose increased with increase of NaOH initial concentration
