OPTIMALISASI TRANSPORT SELEKTIF ION Ni(II) TERHADAP Cd(II) DENGAN ZAT PEMBAWA OKSIN MELALUI TEKNIK MEMBRAN CAIR FASA RUAH SECARA SIMULTAN

ABSTRACT The selective transport of Ni(II) to Cd(II) through simultaneously liquid membrane technique has been investigated. The cell membrane was made by mixturing Ni(II) and Cd(II) ions at concentration as 3.41x10-4 M and 1.78x10-4 M respectively as source phase, oxine in chloroform as membrane ...
