PHYSICO–CHEMICAL STUDIES OF HEAVY METAL IONS SORPTION BY MODIFIED ALUMINUM SILICATES
The paper presents the data of physico–chemical analysis of heavy metal ions sorption with the use of a new type of sorbents – modified zeolites. Infrared spectra of the modified zeolite from the Kholinsky deposit are studied after heavy metal ions adsorption. The energy dispersive spectra of the samples under investigation that prove the fact of heavy metal ions sorption on this kind of sorbents are obtained. The adsorption mechanisms of metals modified by organosilicon compounds are identified. It is proved that the ions of zinc and nickel are absent on the sorbent surface after its regeneration.
