Модификация минерального носителя для придания дополнительных сорбционных свойств

Abstract

Using modified sorbents is one of the most effective methods for water purification from heavy metals. There are variety of methods for surface modification of materials with the purpose of giving them additional sorption properties. The aim of our work is modification of natural hematite surface with nanoparticles oxohydroxide aluminum by the electric spark dispersion method. As a result, physicochemical and sorption characteristics of the modified sorption material were obtained. It was revealed increasing sorption capacity of modified sample with respect to the original sample of hematite.
