摘要
研究了XDA-200大孔树脂对水溶液中邻苯二甲酸的吸附。结果表明XDA-200树脂对水溶液中的邻苯二甲酸吸附速度很快,30min内基本达到平衡,其后达到完全平衡的吸附进程非常缓慢。树脂对邻苯二甲酸的吸附量随质量浓度增加而增加。pH值降低,有利于邻苯二甲酸在溶液中以分子态存在,易于树脂吸附。邻苯二甲酸的吸附均满足Freundlich和Langmiur等温吸附方程。泄漏点与进水浓度和流速均有很大关系。
The adsorption of o-phthalic acid by XDA-200 was tested in a static experiment. The results show that the adsorption of o-phthalic acid from aqueous solution to the macroreticular resin is quick, and an adsorption balance can established between the aqueous and solid phases within 30 minutes, and the balance is agreed with the Freundlich and Langmuir adsorption isotherm.
