摘要

The nature of sorption of Ni~2+ and Cu~2+ ions bythe complex-forming fibrous sorbent Tiopan-1 was studied. Thecomposition and the stability constants of nickel(II) and copper(II)complexes with the functional groups of this sorbent weredetermined. The effects of several factors (solution acidity, initialconcentration of the metal ions, ionic strength of the solution) onthe sorption and complexing properties of the sorbent Tiopan-1 inrelation to Ni~2+ and Cu~2+ ions were studied.
