研究了酸性條件下氯酚在大孔弱鹼樹脂D301上的吸附機理。研究表明,在一定的吸附質濃度及pH值下, D301樹脂對對氯酚和鄰氯酚的吸附量與溶液平衡濃度之間存在良好的線性關係,吸附過程類似於固相萃取過程,且分配係數與相應pH值下X射線光電子能譜(XPS)測得的樹脂上自由叔胺基團含量呈線性關係。In the present study X-ray photoelectron spectroscopy (XPS) was adopted to elucidate sorption mechanism of o-chlorophenol and p-chlorophenol onto a weak anion exchanger D301. The distribution of specific forms of amino groups on D301 was obtained and effect of free tertiary amine group on phenol sorption onto D301 was discussed. The result indicate that less free amino group on D301 caused by external solution with lower pH leads to less sorptive capacity of o-chlorophenol and p-chlorophenol respectively. U...
