Journal Article
Poly(N-vinylpyrrolidone) as metal ion liquid-liquid extractant
2000
Overview
SUMMARYPoly(N-vinylpyrrolidone) (PVP) was investigated as a novel extracting agent. The metal ion extraction properties for Cu(II), Co(II), Ni(II), Cd(II), Zn(II), Pb(II), Hg(II), Cr(III) and Fe(III) were investigated using the liquid-liquid solvent extraction technique (bath method). The metal ion interactions with the polymer were determined as a function of the pH as well as the kinetic characteristic and stripping.For copper ions pH 4 was the optimum extracting pH value, and the 2M hydrochloride acid was better than nitric acid as a stripping agent.
