This paper based on a theoretical study of the supported liquid membrane separation
technology, explores the appropriate liquid membrane separation system, makes a study
on the Pb (II) transmission behavior in the PC-88A-kerosene-HCl dispersion supported
liquid membrane system and reviews influence of the feed liquid pH value, volume ratio
between the membrane liquid and analytic agent, HCI concentration during analytic phase
and initial Pb (II) transmission concentration. The results show that the migration of Pb (II)
is well completed for 190 min with the migration rate being up to 95% on the premise that
the feed liquid pH is equal to 6.0, Pb (II) initial concentration of 3.0 103 mol/L, HCl
concentration during the stripped and dispersed phase is 4.0 mol/L, volume ratio between
the stripped liquid and organic phase is 40:160 and that of the conventional supported
liquid membrane is only 72.4%. The dispersion supported liquid membrane is characterized
by higher transmission efficiency, stable membrane system and long membrane
service life. The procedure has provided accurate results with zinc borne waste water
treatment.
