摘要:

利用乙二胺改性磁性壳聚糖纳米粒子(EMCN)吸附酸性橙7 (AO7)和酸性橙10 (AO10). EMCN制备时先通过在由环已烷/正已醇、壳聚糖和铁盐组成的反相微乳体系中加NaOH溶液沉淀剂, 得到磁性壳聚糖纳米粒子, 再经乙二胺改性以增加氨基含量和提高吸附容量. 透射电镜表明, EMCN分散良好, 粒径15-40 nm. 吸附实验表明, AO7和AO10最佳吸附分别在pH 4.0和pH 3.0. EMCN具有粒径小和高表面活性, 因此吸附速率快. 吸附平衡符合Langmuir模型, AO7和AO10的最大吸附容量分别为3.47和2.25 mmol·g^-1. 热力学分析表明吸附过程放热, 且能自发进行. EMCN可用NH⁴OH/NH⁴Cl (pH 10.0)溶液再生并可重复使用.

Abstract:

Ethylenediamine-modified magnetic chitosan nanoparticles (EMCN) were prepared and used for the adsorption of Acid Orange 7 (AO7) and Acid Orange 10 (AO10) from aqueous solutions. Magnetic chitosan nanoparticles were prepared by adding a basic precipitant NaOH solution to a W/O microemulsion system containing cyclohexane/n-hexanol, chitosan and ferrous salt. This was then modified with ethylenediamine to increase the amine content and to improve the adsorption capacity. Transmission electron microscopy showed that the EMCN was essentially monodispersed and had a main particle size distribution of 15-40 nm. Adsorption experiments indicated that the maximum adsorption capacity was at a pH of 4.0 for AO7 and a pH of 3.0 for AO10. Because of the small diameter and the high surface reactivity of EMCN, the adsorption equilibrium for both dyes was reached very quickly. The equilibrium experiments fitted the Langmuir isotherm model well and the maximum adsorption capacities of 3.47 and 2.25 mmol·g^-1 were obtained for AO7 and AO10, respectively. We estimated the thermodynamic parameters and accordingly the adsorption process was found to be spontaneous and exothermic. Additionally, we regenerated EMCN with an NH⁴OH/NH⁴Cl solution (pH 10.0) and the regenerated material was used to readsorb the dyes.
