Abstract

This paper is devoted to a comparative estimation of selective properties of natural cellulose-containing biopolymers and their modified species at sorption of heavy metal ions from composite salt solutions modelling electrolyte composition of biological media of organism. The modification carried out is based on depolymerisation of macromolecules of cellulose-polysaccharide complexes under various physical and chemical effects, selective oxidizing of alcoholic groups up to carbonyl and carboxyl ones, obtaining esters with compounds containing additional groups with acidic properties. The results of modifying of the vegetative wastes for the purpose of selectivity improvement of sorption are revealed in extraction of heavy metal ions from salt solutions. The components of vegetative raw materials are cellulose and lignin, their fibrillar structure giving a chance to form a developed porous structure of certain type sorption materials.
