Sorption of copper from decontamination solutions using selective sorbents

Popis výsledku v původním jazyce

Copper is one of the radionuclides present in the used decontamination solutions. Its separation is possible through selective sorbents, e.g. chelating sorbents. The most common chelating sorbents have iminodiacetic (IDA) functional group. Another option is to use weakly acidic cation exchangers with carboxylic or phosphonic group. In this study, we observed the sorption of copper ions from a solution of citric acid by five different types of commercial sorbents: Amberlite IRC 748, Amberlite IRC 86, Amberlite IRC 747, Lewatit Mono plus TP 207, Lewatit CNP80. Batch experiments were carried out in aqueous solutions of citric acid of various concentrations and of various pH values for each type of the tested sorbents in order to find practical operating conditions for the selected sorbents. Our results showed that sorbents with IDA funtional group are better option for sorption processes with the presence of citric acid than weakly acidic cation exchangers with carboxylic or aminophosphonic group.
