Methyl orange (MO) dye was removed using Amberlite XAD-2 resin modified by wet impregnation method with Aliquat-336. The modified resin was characterized by FTIR, FE-SEM, SEM with EDX, and pH of zero charge. Experimental parameters such as time, initial dye concentration, pH, temperature, resin dose and presence of NaCl salt affecting the adsorption rate were studied. 2 g.L−1 of resin was found to be optimum for 20 mg.L−1 MO dye. A maximum of 40.93 mg dye was removed per gram of resin. Langmuir, Freundlich, and Temkin isotherms were used to predict the equilibrium points at four temperatures. Pseudo-second-order fitted the kinetic data (R2 = 0.982). The resin could be reused for five successive cycles effectively. Also, the prepared resin was used for the removal of a cationic dye, rhodamine-B and an industrial dye, Pink S8EB.

使用 aliquat 336 浸渍的 Amberlite XAD-2 树脂有效去除甲基橙染料

使用通过湿浸渍法用 Aliquat-336 改性的 Amberlite XAD-2 树脂去除甲基橙 (MO) 染料。改性树脂的特征在于 FTIR、FE-SEM、带有 EDX 的 SEM 和零电荷的 pH 值。研究了影响吸附速率的实验参数,例如时间、初始染料浓度、pH、温度、树脂剂量和NaCl盐的存在。发现2gL -1树脂最适合20mg.L -1 MO染料。每克树脂最多去除 40.93 毫克染料。Langmuir、Freundlich 和 Temkin 等温线用于预测四种温度下的平衡点。拟二阶拟合动力学数据 ( R 2 = 0.982)。该树脂可以有效地重复使用五个连续循环。此外,制备的树脂用于去除阳离子染料罗丹明-B 和工业染料 Pink S8EB。
