The process of removal aluminum and cobalt ions from aqueous solutions with a phosphorus-containing product containing inositol hexaphosphoric acid derivatives obtained from rice production wastes of Far Eastern selection varieties – rice flour, and optimal conditions were determined. It is established that the efficiency of removal of metal cations by the phosphorus-containing product depends not only on their nature, but also on the initial concentration of ions in solutions. The degree of extraction of aluminum ions reaches 99%, and cobalt – 76%. The principal possibility of using phosphorus-containing products of plant origin in the development of environmentally safe materials for the removal of metal ions in technologies requiring the use of green chemistry methodology is proposed.
