Abstract: The adsorption of metal ions from their aqueous solutions on dehydrochlori- nated poly(vinyl chloride) has been experimentally studied and tested by Langmuir's isotherm. It has been found that the amount of Hg(II) adsorbed increases with increasing temperature and the adsorption enthalpy of the process is -17 kJ mol-1. Adsorption on dehydrochlorinated PVC has been observed also in the case of Ag(I), Pb(II), and Fe(II). Ni(II), Zn(II), Pd(II), Ca(II), and Cu(II) exhibit no adsorption.
