摘　　要：以异丙苯为污染物,研究了3种聚氧乙烯醚型表面活性剂的增溶能力、界面张力以及泡沫性能。实验结果表明,脂肪酸甲酯乙氧基化物磺酸盐(FMES)在100 g/L的NaCl溶液中增溶参数为9,油/水界面张力低至0.013 mN/m,且泡沫尺寸最小、最均一,泡沫更稳定,有良好的泡沫性能。以FMES为主剂的泡沫剂体系,在一维填砂管中污染物冲洗率达99%以上。Using cumene as the pollutant,the solubilization power,interfacial tension,and foam properties of three polyoxyethylene ether surfactants were studied.The results show that the fatty acid methyl ester ethoxylate sulfonate(FMES)in 100 g/L NaCl solution has a solubilization parameter of 9,an oil-water interfacial tension as low as 0.013 mN/m.It produces the smallest,most uniform foam which is more stable and exhibits good foam properties.In a foam agent system developed with FMES as the main agent,the pollutant flushing rate reaches more than 99%in one-dimensional sand pack.
