Optimum Conditions for Applying the Magnetic Absorption Methodfor Decontamination of Ferrous Sulphate and Chromate-Containing Wastewater

Abstract

The article deals with the acute issue of intensive contamination of surface and underground waters with iron and chromium ions, which reduces the amount of water suitable for consumption. It was noted that because of monitoring the state of transboundary rivers of Ukraine within the framework of bilateral agreements, an unacceptable excess of the content of heavy metal ions was recorded. The main polluters of the water environment are machine-building enterprises that discharge untreated or insufficiently treated metal-containing wastewater from the process - es of steel etching, chrome plating, etc. Recently, the processing of these solutions to obtain a suspension of highly dispersed particles with magnetic properties – magnetite has been increasingly practiced. One of the directions of its use is the sorption of various pollutants in water environments, i
