INVESTIGATION OF THE PROCESS OFADSORPTION OF HEAVY METAL IONS BYWASTE-BASED COMPOSITE

Sorption characteristics of the adsorbent composite synthesized on the basis of polyvinyl chloride and butadiene-nitrile rubber wastes with respect to cobalt, nickel and zinc ions from aqueous solutions were studied under static conditions.Dependences of the sorption capacity on the solution pH, composite mass, ionic strength of the solution and initial concentration of metal ions were obtained.Sorption isotherms were processed by the Langmuir and Freundlich models.It was found that the sorption of metal ions on the composite is best described by the Freundlich model.
