The
Sorption of Transition Metals and Lead Ions on Carboxymethylcellulose Sorbent
CM-52
Abstract
The complexing properties of
carboxymethylcellulose sorbent CM-52 towards ions of Cu2+,
Co2+, Ni2+, Cd2+, Zn2+, Mn2+ and Pb2+ have been investigated. The optimal conditions of
metal ions sorption from solutions were found; the influence of pH on extracion
degree of metal ions was studied. The maximum extraction of metal ions from
solution is achived at pH higher then 5–6, and at pH lower 1,5 the practically
profound desorption was observed.
