Abstract

Due to the deterioration of natural water quality, the problem of the quality of consumed water is aggravated. Among the methods of water purification are the most promising techniques, based on sorption. Wood-oxidized coal, with its advanced surface and the availability of oxygen-containing functional groups, has good prospects for advanced treatment of water for food industry. The authors investigated the sorption properties of wood-oxidized coal in static conditions for the cations Fe3+, Mn2+, Zn2+, Ca2+, Mg2+ purposely to identify dependence of the concentration this cations in the solution after the contact with wood-oxidized coal on the process period. A result of research has established that sorption of the cations is considered a first-order reactions. The rate constants of the cations sorption Fe3+, Mn2+, Zn2+, Ca2+, Mg2+ on the wood-oxidized coal are estimated. On speed sorption on wood-oxidized coal, these cations can be positioned in a row: Fe3+> Ca2+, Mg2+> Zn2+> Mn2+
