Synthesis and Characterization of Poly (1,4-Benzenedimethylene Phthalate) and the Study of its ability to sorb Pb(II), Cd(II), and Zn(II) ions
Journal Title: Archives of Organic and Inorganic Chemical Sciences - Year 2018, Vol 1, Issue 1
Abstract
Poly (1,4-benzenedimethylene phthalate) was synthesized by condensation of phthaloyl chloride with 1,4-benzenedimethanol in the presence of pyridine in dry THF at 30 °C . The resulting polymer white powder was characterized by viscosity measurement, FT-IR, 1H and 13C NMR, elemental analysis, thermal (TGA-DSC) methods and scanning electron microscopy. The uptake properties of Pb(II), Zn(II) and Cd(II) metals by the polymer from aqueous solutions were studied by the batch and column techniques as a function of pH, temperature, concentration and contact time. The uptake increased with increasing pH reaching a maximum at pH = 6.00 for all ions. The polymer showed high uptake capacities toward Pb(II) and Zn(II) ions, but medium uptake capacity toward Cd (II). The linearized forms of Langmuir, Freundlich and Dubinin-Radushkevich adsorption isotherms indicate studied ions Pb(II), Zn(II), and Cd(II). The adsorption capacity follow the order: Pb(II) > Zn(II) > Cd(II)
