Abstract:

Diaminododecyltetramethylenetetraphosphonic acid (DADTMTPA) has been investigated in liquid - liquid extraction of Zn (II) and Cu (II) in acetate media. The extraction of both cations was carried out in different media with the addition of CH3COONa, CH3COOH, HCl and H2SO4 at different pH values. The maximum extraction yield for copper is 70% after addition of 10 mg of sodium acetate and for zinc is 30% after addition of acetic acid at pHi = 5.5, in one step.

Keywords:

copper (II), DADTMTPA, solvent extraction, zinc (II), diaminododecyltetramethylenetetraphosphonic acid.
