Sulphidation of Cu2+, CuO and Cu2O within the matrix of carboxylic cation exchangers – compositional, morphological and thermal properties of CuxS containing composites

New hybrid cation exchangers containing Cu x S clusters. Sulfidation product depends on the type of HIX and precursor. Copper and sulfur are distributed throughout the entire volume of the HIXs. High thermal stability of of prepared HIXs.
