Pectin–cerium (IV) tungstate nanocomposite and its adsorptional activity for removal of methylene blue dye|
Gupta, V.K.; Pathania, D. & Singh, P.
Pectin–cerium (IV) tungstate composite (Pc/
CT) has been prepared by sol gel method at room temperature.
The composite ion exchanger has been characterized
using X-ray diffraction, scanning electron
microscopy, energy dispersive X-ray spectroscopy and
Fourier infrared spectroscopy. The ion exchange capacity,
pH titrations, thermal stability and distribution coefficient
of composite ion exchanger were investigated. The Na?
ions exchange capacity of the Pc/CT has been observed
higher (1.4 meq g-1) as compared to its inorganic counterpart
(0.8 meq g-1). Pc/CT composite ion exchanger was
thermally stable and retained about 60 % of its ion
exchange capacity up to 400 °C. The distribution study has
inferred more selective the Pc/CT for Zn2+ as compared to
other metal ions. The adsorption efficiency of Pc/CT was
tested for methylene blue removal dye from aqueous phase.
The removal of dye followed pseudo-second-order
