Thermo- and mechanochemical modification of glauconites and theirsorption property
Abstract
With aim of usage of glauconites as a K-fertilizers and microfertilizers the sorption properties of modified glauconite with respect to ions of Zn, Mn, Ni, Cu, Co (II), containing in insufficient quantity in most soils of Republic of Kazakhstan were studied.
The phase composition of glauconite changes at the thermal modification and the sorption properties decrease. It was found that mechanochemical modification with the addition of NaH2PO4 has the maximum effect of sorption (αsorb. = 94.9%) because of the transition of the Ca – form of glauconite to the Na-form.
