Effect of Surfactant on the Volatilization of Organochlorine Pesticides from Still Artificial Seawater
十二烷基苯磺酸钠对有机氯农药在模拟的静海水水面挥发的影响

The effect of sodium dodecylbenzene sulfonate(SDBS) on the volatilization of 17 organochlorine pesticides(OCPs) from still artificial seawater has been examined.The results show that SDBS at low concentration can retard the volatilization of OCPs compared to "clean" surface.The retarding influence is more pronounced for high level of SDBS than it is for low level of SDBS.A good positive correlation between the gas-seawater partition coefficients and the measured volatilization rates of OCPs is observed.Alth...
