The redox potentials of chloroform are more than 500mv and electrosorption is only controlled by electric field and adsorption of granular activated carbon . the tests of adsorptions also testify it . the freundlich isotherm equation q = kc n is used for fitting the data 另外，氯仿的电解氧化还原电位大于500mv ，因此，此电场范围不会分解氯仿，回收率实验与色谱分析也证明了电场只对活性炭的吸附起催化作用，而不改变吸附剂与吸附质的内部性质。
