Physico-chemical properties new nitrogen- and phosphorus containing ion exchange resine on the base of polyvinylchloride

Peculiarities of the interaction of PPE-1 anion exchange resin with phosphonic acid production based on granular polyvinyl chloride were studied. As a result of the modification, a polyampholite was obtained in terms of physicochemical properties not inferior to the industrial polyampholite APFC-45. We also investigated the sorption of copper (II), nickel (II) and indium (III) ions on a polyampholite based on granular polyvinylchloride. The dependence of static adsorption on aqueous solutions on the concentration of metal ions and the temperature of the system is established. Isotherms were constructed and found the adsorption equilibrium constants, the thermodynamic parameters of the process - isobaric - isothermal potential (ΔG), enthalpy (ΔH) and entropy (ΔS). It is shown that the investigated sorbent absorbs ions Cu (II) to a greater extent than the other ions.
