Abstract

The influence of the composite content of montmorillonite − polyvinyl alcohol on physico-chemical and adsorption properties of resultant granular sorbents for removing cobalt (II) ions and cationic dye of methylene blue from aqueous solutions is first given in the paper. For studying the basic properties of the resultant materials, the X-ray phase analysis and sorption methods were used.

It was shown that the optimum content of montmorillonite in granular composite is 38 %. Increasing the montmorillonite content does not significantly affect adsorption properties and water absorption. The results of the X-ray phase analysis indicate the penetration of polyvinyl alcohol molecules in the interlayer space of the mineral, leading to a change in the respective basal reflections in the diffractograms. It was found that the granular composite of montmorillonite and polyvinyl alcohol have relatively high adsorption characteristics relative to the removal of cobalt ions and methylene blue in a wide range of pH solution. The research results can be useful to obtain and study the basic properties of granular sorbents for extracting cations and cationic dyes from aqueous solutions.
