| 摘 要： | 采用一次平衡法初步研究了土娄土对十六烷基三甲基溴化铵(CTMAB)的吸附机制。结果表明,土娄土对CTMAB的吸附等温线属于S型,吸附量和吸附力很大;pH增加,土壤对CTMAB的吸附量略有增加;CTMAB在土壤表面是多层吸附,以单分子或二分子缔合体的形式吸附于土壤表面;CTMAB在土壤-溶液体系的临界表面胶团浓度smc显著小于溶液体系CTMAB的临界胶团浓度cmc。

| Abstract: | The adsorption of cetyltrimethylammouium bromide in old manured loessal soil was studied by equiliibrium method.Results showed that the adsorption isotherms belonged to S type,the adsorbed amount and adsorbed affinity were very high.The adsorbed amount increased slightly with the increase of pH.CTMAB adsorption in soil was multi-layer,CTMAB with single molecule or double molecule combination was adsorbed by soil.Surface micelle concentration(smc) of CTMAB in soil-solution system was obviously less than critical micelle concentration(cmc) of CTMAB in solution. |
