Abstract: The hydroxylation ionic liquid-iron coordination complexes (HILICC) with ionic liquid 1-butyl-3- methylimidazolium and OH groups as ligands were synthesized and then were explored as adsorbents to recover the reactive blue 19 dyes from the dyeing wastewater. The effect of adsorption time, temperature, dye concentration and pH on the adsorption efficiency was investigated. An adsorption efficiency of ca 98% was achieved when 3.0 ml of 0.05 g·L-1 reactive blue 19 dye under pH for 4—5 was adsorbed by 0.02 g HILICC. The desorption efficiency of reactive dyes were more than 60% and recovery efficiency was more than 54% when the 3.0 ml of 0.1 mol·L-1 NaOH solution was applied to desorb 0.02 g HILICC.

摘要: 以离子液体1-丁基-3-甲基咪唑溴代盐为原料, 合成含有离子液体咪唑基团和羟基基团的羟基化1-丁基-3-甲基咪唑离子液体铁配合物, 并将其用于活性染料的吸附。考察了该离子液体铁配合物对活性蓝19的吸附影响因素及吸附类型。结果表明当离子液体铁配合物的用量为0.02 g, 在pH为4~5, 活性蓝19染料的浓度为0.05 g·L-1, 体积为3.0 ml, 吸附时间为15 s时, 离子液体铁配合物对活性蓝19染料的吸附率为98%。以0.1 mol·L-1 NaOH作为解吸剂, 可实现对吸附的活性蓝的洗脱, 解吸率为60%, 活性蓝19的回收率为54%。基于以上吸附方法, 可实现对印染废水中活性蓝19染料的回收。
