In the present study, a Schiff’s base polymer (SBP) has been synthesized by the condensation of trifluoroacetylacetone and amino-polystyrene copolymer resin. After the characterization of synthesized polymer by FT-IR spectroscopy, thermal and elemental analyses, the removal of 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP) along with phenol is optimized using response surface methodology. Eighteen runs design were performed with different levels of variables in order to optimize sorption parameters such as pH, concentration of adsorbate, agitation time and amount of polymeric resin SBP. Maximum Langmuir sorption capacity obtained was 110.7, 125.3 and 195.4 mg g −1 , for phenol, 2-CP and 2,4-DCP, respectively. Recovery of adsorbed phenol, 2-CP and 2,4-DCP was checked by different solvents and was found to be quantitative (~ 99%) with methanol. The model was validated by performing sorption experiments at optimum conditions. Kinetic and isotherm studies of all three analytes on SBP are also discussed.

一种新的 Schiff 基础聚合物，用于修复受污染的水系统中的苯酚、2-氯苯酚和 2,4-二氯苯酚

在本研究中，通过三氟乙酰丙酮和氨基-聚苯乙烯共聚物树脂的缩合合成了席夫碱聚合物 (SBP)。通过 FT-IR 光谱、热分析和元素分析对合成聚合物进行表征后，使用响应面方法优化去除 2-氯苯酚 (2-CP)、2,4-二氯苯酚 (2,4-DCP) 和苯酚. 为了优化吸附参数，如 pH 值、吸附物浓度、搅拌时间和聚合树脂 SBP 的量，进行了 18 次运行设计，其中包含不同水平的变量。对于苯酚、2-CP 和 2,4-DCP，获得的最大朗缪尔吸附容量分别为 110.7、125.3 和 195.4 mg g -1 。吸附的苯酚、2-CP 和 2,4-DCP 的回收率通过不同的溶剂进行检查，发现使用甲醇是定量的 (~ 99%)。通过在最佳条件下进行吸附实验来验证该模型。还讨论了 SBP 上所有三种分析物的动力学和等温线研究。
