Application of ion exchange resins to recovery of metals from decontamination solutions
Original language description
Three ion exchange resins were used for the selective removal of nickel (II), copper (II), cobalt (II), zinc (II), manganese (II) and iron (III+II) from synthetic solutions simulating AP-CITROX decontamination solution. In this study, we tested two chelating resins; Dowex M4195, Lewatit MonoPlus TP207 and strongly acidic cation exchange resin Lewatit MonoPlus SP112, all promising in acidic solutions. The efficiencies of resins were tested in column experiments. The aqueous samples were analyzed by atomic absorption spectroscopy. The chelating resin, Dowex M4195 showed the best results for nickel, cobalt, copper and iron selective sorption from model solution. On the other hand the metal removal by Lewatit MonoPlus TP207 was not efficient. The zinc and manganese sorption results onto Lewatit MonoPlus SP112 were very promising. Thus, to achieve high selectivity of extracting tested metals we tried the series column circuits with DowexM4195 and Lewatit MonoPlus SP112. Based on this study, it would appear that treatment of mixed metal wastes, generated by APCITROX decontamination process, by ion exchange resins is a technically feasible process for removal and separation of metals, even in lower pH, such as pH=1.
