p-Dichlorobenzene (p-DCB) was eluted through a compacted ferruginous clay with dilute aqueous solutions of methanol, ethanol, n- and i-propanols, and n- and i-butanols. The presence of the alcohols results in very marked increases in the concentrations of p-DCB in the effluents from the clay-packed columns. Flux of p-DCB through the columns increases with increasing chain length of the alcohol, and normal alcohols increase the flux somewhat more than corresponding branched alcohols. Flux increases with increasing mole fraction of the alcohol. Flux enhancement is due almost exclusively to enhancement of the solubility of p-DCB.
对二氯苯（p-DCB）用甲醇、乙醇、正丙醇和异丙醇以及正丁醇和异丁醇的稀水溶液从压实的铁粘土中洗脱出来。醇的存在导致 p-DCB 在从粘土填充柱中流出的溶液中的浓度非常显著地增加。p-DCB 通过柱的通量随醇链长的增加而增加，并且正醇比相应的支链醇稍微增加通量。通量随醇的摩尔分数的增加而增加。通量增强几乎完全是由于 p-DCB 的溶解度增强所致。
