CAUSTOBIOLITHES HYDROLYSIS REMNANTS AS RAW MATERIALS FOR HEAVY METAL IONS SORBENTS PRODUCTION
Results of experimental researches of the structure of functional groups composition and sorption activity to ions of heavy metals of peat and brown coal hydrolysis are given. It has been found that sorption activity of peat and brown coal hydrolysis increases at the transition from acidic to neutral medium reaction and decreases in relation to heavy metals ions in the series Cu<sup>2+ </sup>> Ni<sup>2+ </sup>> Zn<sup>2+</sup>. It has been revealed that the remnant updating after hydrolysis by ultrasound enhances more than twice its sorption capacity.
