摘要：

Transport behavior of Pt(IV) from bromide media through a liquid emulsion membrane has been studied using Cyanex-923 as a mobile carrier. Platinum(IV) was quantitatively extracted from external bromide (feed phase) media and stripped in perchloric acid as an internal (strip) phase. The important variables governing the permeation of Pt(IV) through LEM studied are membrane viscosity, concentration of mobile carrier, treatment ratio, speed of agitation, and internal (strip) phase concentration. The optimum condition for extraction of Pt(IV) via liquid emulsion membrane are-internal phase: 4.0 mol dm(-3) HClO4; organic phase: 12% span-80, 7% 1-octanol, and 0.8% Cyanex-923 in xylene; feed phase: 10 ppm of Pt(IV) in 5.0 mol dm(-3) HBr in presence of 0.005 mol dm(-3) SnCl2.
