Electrical conductivity and ion-exchange kinetic studies of polythiophene Sn(VI)phosphate nano composite cation-exchanger

摘要: Abstract A polymeric hybrid nanocomposite, namely polythiophene tin(IV)phosphate (PTh–SnP), was expediently synthesized by incorporating (PTh) in tin phosphate (SnP) to enhance the conducting behavior and sorption of heavy metal ions porous cation exchanger. Composite characterized Fourier Transform-Infra Red Transmission Electron Microscopy. The dc electrical conductivity studies carried out on composite, showed within range 4.0 × 10 − 2 –1.0 × 10 3  S/cm 1 ; measured a 4-in line-probe measuring technique. Ion-exchange kinetics for few divalent evaluated particle diffusion-controlled ion-exchange phenomenon at four different temperatures. diffusion mechanism is confirmed linear τ (dimensionless time parameter) vs t (time) plots. exchange processes thus controlled exchanger systems herein. Some physical parameters like self-diffusion coefficient ( D 0 ) , energy activation E entropy (Δ S °) have been under conditions favoring mechanism.
