苯乙腈类有机污染物的溶解度、吸附系数与分配系数的相关性
- SOLUBILITIES, ADSORPTION COEFFICIENTS AND PARTITION COEFFICIENTS OF PHENYLACETONITRILEAND ITS DERlVATES
- 摘要:分配系数、溶解度和土壤/沉积物吸附系数存在着相关性。对这些相关性进行研究具有重要的意义。正辛醇/水分配系数与生物浓缩因子(BCF)有关,反映了水生生物对有机污染物的富集作用。
- Abstract:Water solubilities (S) and adsorption coefficients (Koo) on lake sediment of a number of phenylacetonitrile derivates were determined. It was found that the measured Sw and Koo are related to octanol/water partiti-on coefficients (Kow) by the equations, log (1/SW) = 0.963log (Kow) -5.047 and log (Koo) = 0.556log(Kow) + 1.142, respectively.
