| Summary: | In this paper,
characteristics of the interaction of an anion-exchange resin PPE-1 formed
using phosphonic acid and granular polyvinyl chloride were investigated. In
addition, a reaction order of 1.43 and an activation energy of 47.8 kJ/mol for
phosphorylation were determined. The as-obtained polyampholyte was
characterized by scanning electron microscopy (SEM), energy-dispersive X-ray
(EDX) analysis, and Fourier transform infrared (FTIR) spectroscopy. Optimum
conditions for obtaining a new polyampholyte that selectively adsorbs
non-ferrous metal ions on the basis of granulated polyvinyl chloride were
determined. Sorption isotherms for
non-ferrous metal ions were constructed, which were reasonably explained by
Langmuir isotherms. Various thermodynamic parameters, such as
isobaric-isothermal potential (?G), enthalpy (?H), and entropy (?S), were
calculated to understand the nature of sorption. The examined polyampholyte
selectively absorbed copper(II) ions. |
