摘要

层状双氢氧化物(LDHs)是广泛应用于亚甲基蓝去除的吸附剂。然而,LDHs具有不能重复使用的易损坏结构。壳聚糖改性LDHs可制备一种具有大表面积的强吸附亚甲基蓝材料。通过测定吸附等温线和吸附剂再生过程,优化了吸附条件。结果表明,该吸附过程在90 min内达到平衡,对Zn/Al、壳聚糖和Zn/Al-壳聚糖的最大吸附量分别为86.207 mg/g、35.336 mg/g和98.039 mg/g。本研究采用Freundlich等温吸附模型。对吸附剂的再生分析表明,锌/壳聚糖可重复用于亚甲基蓝的吸附。

Preparation of Zn/Al-chitosan Composite for the Selective Adsorption of Methylene Blue Dye in Water
Layered double hydroxide (LDHs) are widely used adsorbents for methylene blue removal. However, LDHs have a perishable structure that cannot be used repeatedly. Modifying LDHs with chitosan produces a strong material with a large surface area for methylene blue adsorption. Adsorption conditions were optimized by determining the adsorption isotherms and the adsorbent regeneration process. Results showed that the adsorption process was balanced in 90 min with maximum adsorption capacities of 86.207 mg/g, 35.336 mg/g, and 98.039 mg/g for Zn/Al, chitosan, and Zn/Al-chitosan, respectively. The adsorption in this study followed the Freundlich isotherm model. Regeneration analysis of the adsorbent showed that Zn/Al-chitosan can be used repeatedly in methylene blue adsorption.
