Abstract

In this study, polymeric cryogels were synthesized to develop a new methacrylamide-based polymeric material that includes chitosan to remove dyes that may be present as contaminants in aqueous media. Methacrylamide/chitosan (MAmCS) cryogels prepared under cryogenic conditions were characterized by FTIR, SEM/EDX and swelling tests. It was determined that the Langmuir isotherm model, pseudo second order and intra-particle kinetic models were found to be the best fit models to describe adsorption between polymeric cryogels and anionic dye calconcarboxylic acid (CCA). The results showed that the cryogels obtained can be used as an alternative adsorbents for the treatment of wastewater containing pollutant species from different industries and may help other applications in the design of MAmCS polymeric materials.

甲基丙烯酰胺/壳聚糖聚合物冰晶的合成及溶胀/染料吸附性能

摘要

在这项研究中,合成了聚合物冰凝胶以开发一种新的基于甲基丙烯酰胺的聚合物材料,其中包括壳聚糖以去除可能在水性介质中以污染物形式存在的染料。通过FTIR,SEM / EDX和溶胀测试对在低温条件下制备的甲基丙烯酰胺/壳聚糖(MAmCS)冷冻凝胶进行了表征。已确定,Langmuir等温模型,伪二级和颗粒内动力学模型是描述聚合物冰晶凝胶和阴离子染料钙碳羧酸(CCA)之间吸附的最佳拟合模型。结果表明,所获得的冰凝胶可以用作替代吸附剂,用于处理来自不同行业的含污染物物种的废水,并可能有助于MAmCS聚合物材料设计中的其他应用。
