Maletskyi Z. Hybrid sorbents and their application for water purification aimed to Iron and Arsenic

Physicochemical and sorption characteristics of hybrid sorbents based on anion exchangers and humic substances are defined and technologies of water purification aimed to iron and arsenic impurities applying mentioned hybrid sorbents are designed. Mechanisms of interaction between anion exchangers and humic substances together with processes of iron and arsenic sorption by hybrid sorbents have been studied. Processes of deep water purification aimed to impurities of iron and arsenic are designed, and rational conditions for their implementation are defined. Feasibility of hybrid sorbent choice for the use in the technology of deep water treatment aimed to arsenic impurities has been given. Depending on the form of arsenic presence in the water and its concentration the cost of treated water can be reduced by 2,5-5 times in the case of hybrid sorbent application.
