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 500ºC of its loss less than 10 % makes.
