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. (C) 2010 Elsevier B.V. All rights reserved.
