摘要
通过振荡平衡法研究了不同浓度的阳离子表面活性剂十六烷基三甲基溴化铵(HDAB)对五氯酚钠(PCP-Na)在土壤中吸附的影响。结果表明:土壤本身对五氯酚钠有一定的吸附能力,阳离子表面活性剂HDAB的存在增加了土壤对PCP-Na的吸附能力,且随着HDAB加入量的增多而增加。不管HDAB的加入量多少,PCP-Na在土壤中的吸附符合Fre-undlich等温方程。图2,表1,参9。
The influence of the different concentration of surfactant-bmmide hexadecyltrime thyl-ammoniun （HDAB） on the adsorption of PCP-Na in soil was studied. The results indicated that the PCP-Na can be definitely adsorbed by soil , HDAB can increase adsorption of PCP-Na in soil , and the increase of adsorptive ability of PCP-Na in soil has linear relation with the added concentration of HDAB.The isotherm data were fitted to the freundlich equation.
