Ecological Systems and Devices Annotation << Back SORPTION CONCOCTION OF SOME IONS OF HEAVY METALS ON NATURAL MATERIALS OF THE ASTRAKHAN REGION V.V. Shakirova, O.S. Sadomtseva, L.A. Dzhigola, R.N. Beysova, R.R. Shamsuarova, E.A. Syutova In view of high toxicity of heavy metals, their sorption concoction for the purpose of the subsequent remove from objects of environment or for the purpose of defi nition of their contents is one of the most important problems of modern ecology and analytical chemistry. This work is devoted to use of clays of the Astrakhan region, and also establishment of the corresponding physico-chemical basis, for the purpose of the solution of a number of the environmental problems connected with cleaning of natural and sewage from ions of heavy metals. Results of the this work, allow to draw conclusions, that absorbing ability of clays of the Astrakhan region is rather high in relation to ions of heavy metals, and can be used as sorbents for the creation of test methods for the determination using sorption concentration, as well as remove toxins from the waste treatment of industrial enterprises. Keywords: heavy metals; adsorption; clays; sorbent; concentration; natural waters; sewage. Contacts: E-mail: svv_2004@mail.ru, E-mail: djegola@mail.ru Pp. 34-39.
