Sorption of heavy metals from aqueous solutions using different types of sorbents

Popis výsledku v původním jazyce

Metals transported into the environment through industrial, agricultural processes or waste dis-posal have a large effect on public health and the economy. In this study, we observed the sorption of Ni, Cu and Fe ions from solutions of citric acid by three different types of chelating sorbents: Amberlite IRC 748; Lewatit Mono plus TP 207 and Dowex M4195. Another tested sorbents were weakly acidic cation exchangers with carboxylic functional group: Lewatit CNP 80 and Amberlite IRC 86. Undesirable ions were separated from the aqueous solutions in both batch and column experiments. The aqueous samples were analysed by atomic absorption spectroscopy. Experiments were carried out in aqueous solutions with different concentra-tions of citric acid and various pH values for each type of the tested sorbent in order to find practical operat-ing conditions. Sorption efficiency and sorption kinetics were measured. The operating conditions of sorption process were discussed in this paper.
