摘　　要：研究了1,2,4,5-四氯苯在C18膜/水相之间的分配规律。1,2,4,5-四氯苯在25℃,80 r/min条件下恒温震荡96 h可达分配平衡,温度和盐度对1,2,4,5-四氯苯C18膜/水的分配过程影响很小,1,2,4,5-四氯苯C18膜/水分配平衡时间受溶液体积和容器容积的影响,但不受溶液中C18膜膜量的影响,推测脂溶性小于或接近1,2,4,5-四氯苯的有机污染物在恒温震荡条件下C18膜与水之间的分配96 h可达到平衡。The partition between C18 membrane and water of 1, 2, 4, 5-tetrachlorobenzene was studied. The results showed that partition equilibrium was established in 96 hours at 25℃,80r/min with little effect by temperature and salinity. The volumes of solution and container affected time of the partition equilibrium but the mass of C18 membrane not. It was supposed that the partition equilibrium between C18 membrane and water was reached within 96 hours for those organic pollutants which polarities were less than or similar to 1, 2, 4, 5-tetra- ehlorobenzene in the condition of constant temperature and oscillating.
