The Sorption Properties of Ukrainian Saponite Clay In Situ Modified of Poly4-Methacroyloxy-(4'-Carboxy-2'-Nitro)-Azobenzene to Toxic Metals Ions

摘要

1 Introduction The high level of contamination of Ukraine's natural waters with heavy toxic metal ions due to the long-term discharge of wastewater makes it urgent to search for new low-cost non-toxic materials that can be effectively used as sorbents for the removal of these ions from wastewater or contaminated natural water. For this purpose, it is advisable to use porous natural minerals, whose tonnage deposits are found in our country, including clinoptilolites, bentonites, saponite clays, etc.
