Abstract: | Carboxymethyl cellulose Sn(IV) phosphate composite nano-rod like cation exchanger with diameter in the range of 20–40 nm,
length in the range of 100–150 μm and particle size in the range of 21–38 nm have been successfully prepared by surfactant
assisted sol–gel method. Scanning electron microscopy, transmission electron microscopy, X-ray powder diffraction, fourier
transform infra red spectroscopy and thermogravimetric analysis-differential thermal analysis studies were carried out to
study the structure and morphology of this composite nano-rod like cation exchanger. Freundlich adsorption isotherm is well
fitted for the adsorption of pyridine on the surface of this composite nano-rod like cation exchanger. The thermodynamic parameters
such as Freundlich constant, thermodynamic equilibrium constant (K
0), standard free energy changes (ΔG
0), standard enthalpy changes (ΔH
0) and standard entropy changes (ΔS
0) have been evaluated. These parameters indicated that the adsorption of pyridine on the surface of composite nano-rod like
cation exchanger was feasible, spontaneous and exothermic in nature which suggests for the potential application of pyridine
removal from water. |
