The adsorption-desorption characteristics of three selected PCB isomers on a soil and some of its constituents have been determined. The extent of adsorption for all surfaces follows the sequence hexachloro greater than tetrachloro greater dichloro for the isomers chosen. For an individual isomer, the adsorption rates increase in the following sequence: Del Monte, sand, illite clay, Woodburn soil, and humic acid. These results are discussed relative to environmental transport of the chemicals.
已测定了三种选定的多氯联苯异构体在一种土壤及其某些成分上的吸附-解吸特性。对于所选的异构体，所有表面的吸附程度顺序为六氯异构体大于四氯异构体大于二氯异构体。对于单个异构体，吸附速率按以下顺序增加：德尔蒙特土壤、沙子、伊利石粘土、伍德本土壤和腐殖酸。结合这些化学品在环境中的迁移对这些结果进行了讨论。
