Dinu %J Ion Exchange Letters %D 2009 %I Department of Power Engineering, Institute of Chemical Technology %X Ionic hybrids based on chitosan and clinoptilolite with sorption capacity for copper(II) ions higher than that of cross-linked chitosan are presented in the paper. Hybrids based on chitosan and clinoptilolite were characterized by swelling degree in water as a function of pH, and by the sorption and desorption of copper(II). %K chitosan %K clinoptilolite %K ionic hybrid %K copper(II) %K sorption %U http://iel.vscht.cz/articles/1803-4039-02-0015.pdf
