Interactions of metal ions sorbed on chitosan beads Original Research Article

In this study, experiments were carried out to estimate sorptivity of chitosan beads and their selectivity towards Cu2+ (copper sulfate), Zn2+ (zinc sulfate) and Cr6+ (potassium dichromate) ions. Studies were performed in the concentration range from 20 to 500 mg/dm3 for single ions and their binary and ternary mixtures in aqueous solutions. A quantitative description of sorption isotherms of the analysed ions in the presence of one or two additional ions in the solution is considered. In this case the application of a neural network MLP was proposed.
