Kinetika dan mekanisme sistem transpor Cd(II) antar fasa melalui teknik membran cair fasa ruah dengan oksin sebagai zat pembawa

ABSTRACT The transport and separation of Cd(II) through bulk liquid membrane technique had been investigated and optimised. Cd(II) was transported through a liquid membrane of chloroform solution containing oxine as mobile carrier and received by EDTA in stripping phase. In compliance with op...
