英文摘要	The sorption enhancement of o-nitroaniline on a soil by the addition of a mixture of a cationic surfactant (cetyl pyridinium chloride, cpc) and a nonionic surfactant (polyethylene glycol mono-4-nonylphenyl ether. p0707), as compared with that by individual cpc and p0707, was investigated to examine their potential application in soil retarding for organic contaminants. the maximum sorption coefficients (k(d)*) of o-nitroaniline on modified soils by individual cpc and p0707 were 110 ml g(-1) at an added cpc dose of 6000 mg l(-1) and 12.5 ml g(-1) at an added p0707 dose of 7000 mg l(-1), respectively. they were approximately 78 and 8.87 times higher than the sorption coefficients (k(d)) of o-nitroaniline on the unmodified soil (1.41 ml g(-1)), suggesting that cpc and p0707 can enhance the sorptive capacity of soil for o-nitroaniline. the maximum k(d)* value of o-nitroaniline on modified soils by the mixture of cpc and p0707 was 144 mg l(-1) (at cpc dose of 10,500 mg l(-1) and p0707 dose of 6000 mg l(-1)), which is higher than that on the cpc (or p0707) modified soils and approximately 102 times higher than that on the un-modified soil. therefore, mixed cationic-nonionic surfactants could be better than individual ones in soil modification to enhance retention of organic contaminants.
