摘要
研究了不同条件下XDA-200大孔树脂对水溶液中苯酚的吸附行为。结果表明,XDA-200树脂对水溶液中苯酚的吸附速率很快,180min内基本达到平衡。树脂对水中苯酚的吸附量随其初始浓度的增加而增加,呈线性关系。pH和温度降低,有利于树脂吸附苯酚。Freundlich模型能够很好地用来描述大孔树脂对苯酚的吸附过程。动态吸附的研究表明泄漏点与进水浓度和流速均有很大关系,乙醇的脱附效果优于氢氧化钠(NaOH)。
The adsorption of phenol by XDA-200,Macroreticular resin was carried out through static and dynamic experiments. The results showed that macroreticular resin for adsorption of phenol from aqueous solution adsorbed very quickly within 180 minutes and reached basic balance. With the mass concentration increasing the static adsorption capability for adsorption of phenol by macroreticular resin increased.The adsorption date fit the Freundlieh adsorption isotherm well. Decreasing of temperature and pH was favor of adsorption.The concentration and adsoption flow rate can affect the adsorption. Desorption effect of alcohol was better than that of NaOH.
