Studies were reported of the variation of canon transport rate through a bulk liquid membrane containing crown functionalized linear polysiloxanes with the kind of polysiloxanes and carrier concentration,canon type and anion type,and with salt concentration. The stability of the membrane was also investigated. 有机硅聚合物冠醚 离子载体 液膜 crown functionalized organosilicon polymer ionophore liquid membrane O484.3 1995-06-01 2021-04-01 6
