[Transfer of Pb(II) through the liquid membrane with alkylphosphonic acid as carrier].
The transfer behavior of Pb(II) through the bulk liquid membrane system of PC-88A-CHCl3 was studied. The study include to analysis the effect of Pb(II) transport rate of the pH values in external aqueous phase, carrier concentration, temperature and external aqueous phase concentration. The results showed that the transport rate of Pb(II) markedly raised with the carrier concentration and temperature. The transfer rate can reach 100% under the condition of pH values 2.8-4.0, carrier concentration 5.00%-7.00% and temperature 289 K-303 K.
