Abstract: Zinc(II) was transported selectively from the feed compartment to the stripping compartment through the flat sheet supported liquid membrane loaded with 2-ethylhexyl phosphonic acid mono 2-ethylhexyl ester (Ionquest801-IQT801) in kerosene. The effects of feed phase pH (1.5-3.0), carrier concentration (5-20 per cent) and stripping agent concentration (0.3-1.3M) were studied using flat sheet supported liquid membrane (FSSLM) and the enrichment factor values were calculated. Second order polynomial regression was used for analysis of the experiment. The experimental values were in good correlation with predicted values and the high correlation coefficient obtained proved the fitness of the selected model.
