对比Zn2+、苯酚、CTAB单元和复合污染物在煅烧高岭土上的吸附，探讨了在不同投加量和pH条件下复合污染共存在煅烧高岭土上的吸附影响．结果表明：单一存在的Zn2+、苯酚和CTAB去除率分别为95.98%，72.73%,和90.50%,；复合污染物体系中的Zn2+、苯酚和CTAB去除率分别为92.12%,，83.60%,和88.27%,，这表明Zn2+和CTAB产生拮抗效应，而复合污染体系促进了苯酚的吸附．由红外分析可知复合吸附后 Si—O(990,cm-1)的伸缩振动峰发生较大的偏移， C—H(818,cm-1)振动峰消失，表明存在化学吸附．
對比Zn2+、苯酚、CTAB單元和複閤汙染物在煅燒高嶺土上的吸附，探討瞭在不同投加量和pH條件下複閤汙染共存在煅燒高嶺土上的吸附影響．結果錶明：單一存在的Zn2+、苯酚和CTAB去除率分彆為95.98%，72.73%,和90.50%,；複閤汙染物體繫中的Zn2+、苯酚和CTAB去除率分彆為92.12%,，83.60%,和88.27%,，這錶明Zn2+和CTAB產生拮抗效應，而複閤汙染體繫促進瞭苯酚的吸附．由紅外分析可知複閤吸附後 Si—O(990,cm-1)的伸縮振動峰髮生較大的偏移， C—H(818,cm-1)振動峰消失，錶明存在化學吸附．

After a comparison of the effect of adsorption on calcined kaolin among Zn2+,phenol,CTAB units and the ternary combined pollutants,this paper explored the adsorption effect on the calcined kaolin in different dosages and pH values. The removal rates of Zn2+,phenol and CTAB were 95.98%,72.73%and 90.50%in the single pollutant system;the removal rates of Zn2+、phenol and CTAB were 92.12%,83.60%and 88.27%in the multi-pollutant system. It demonstrates that Zn2+and CTAB produced antagonistic effect;meanwhile,multi-pollutant system promoted the adsorption of phenol. By infrared analysis,it showed that after compound adsorption,the stretching vibration peak of Si-O(990 cm-1)produced a larger de-viation,and the vibration peak of C-H(818 cm-1)disappeared. It showed that there was chemical adsorption.
