Sorption of copper(II) ions by bismuthol i immobilized on natural zeolyte

Abstract

By immobilization of bismuthol I on natural zeolyte is received a sorbent for extraction of heavy metals from solutions. The optimum conditions sorption of copper(II) ions are found. In static conditions pH 5, time of contact of phases for achievement of balance 140 mines. In dynamic conditions the influence of a nature of the solvent and way impregnation of zeolyte by a solution bismuthol I is shown , and also concentration of copper ions on sorption. Is established, that at copper desorption by thermal processing of sorbent at 500єC of its loss less than 10 % makes.
