摘要:
采用树脂吸附法对苯甲醇废水进行处理,考察了初始质量浓度、吸附时间、酸度、吸附剂用量、盐浓度等因素对NAD-150 超高交联树脂吸附苯甲醇的影响,探讨了NAD-150 超高交联树脂对苯甲醇的解吸附行为和重复利用效果. 研究结果表明NAD-150对苯甲醇的最大吸附量为663.91 mg/g,树脂对苯甲醇的吸附速度快,吸附在60 min内完成并符合准二级动力学模型. 在所研究的范围内,酸度(pH 3~10)对苯甲醇吸附容量的影响小,盐浓度包括NaCl和Na2CO3对苯甲醇的吸附呈现正效应,苯甲醇的吸附量随着盐浓度的增大而显著增大,该吸附剂可用于高盐苯甲醇废水的处理中. 树脂的解吸附实验结果表明饱和吸附的树脂可采用乙醇水溶液进行再生,再生后的树脂可重复使用.
Abstract:
We used resin absorption method?to treat benzyl alcohol wastewater. The effects of initial mass density, adsorption time, pH, adsorbent dosage and salt concentration on the adsorption of benzyl alcohol on NAD-150hyper-cross linked resin were investigated, and the desorption behavior and reuse of the resin were also studied. Results show that the adsorption capacity of the resin for benzyl alcohol is 663.91 mg/g, and the adsorption process is fast and completed within 60 min, which can be described well by pseudo-second order kinetic model. In the investigated range, pH(3-10)has little effect on the adsorption of benzyl alcohol, however, thesalt concentration (NaCl and Na2CO3) has great influence on it. The amount of benzyl alcohol adsorbed increase linearly with the increase of the salt concentration, and the resin can be used in the hyperhaline benzyl alcohol wastewater treatment. Desorption experiment results show that the saturated resin can be reused after regeneration by ethanol-aqueous solution.
