    The colloidal liquid aphrons(CLA) have been prepared. Their sizes and viscosities are mainly affected by the phase volume ratio(PVR). It is found that the stable CLA system capsulated with N1923 or TBP and the CLA with P507 show a good extraction ability for acetic acid and rare earth ions (Y3+, Nd3+, Yb3+), respectively.
    制备了包含萃取剂的胶质液态泡沫(CLA),测定了包含N1923或TBP的CLA萃取醋酸的性能,以及包含P507的CLA萃取稀土离子时稀土在CLA水质滑腻壳层中的渗透系数.结果表明将萃取剂包含于CLA中,对其粒径、粘度及稳定性等不产生明显影响,但对萃取分配及传质十分有利.

    Acetic acid was bonded to Aliquat 336 by both ion exchange and chemical association,and diluent affected their parameters obviously. The apparent constant of ion exchange,K 1,increased in diluent,especially in chloroform. The apparent constant of association,K 2,increased in chloroform also,decreased in n-octanol,and kerosene affected K 2 not apparently.
