Abstract:
The aim of this research work is to investigate sorption characteristic of synthesized polypyrrole / polyaniline (PPy / PANI) nano fiber for Cu (II) removal from paper mill wastewater. The sorption is carried out by batch method. The structural characterization of this sorbent was performed by SEM and FTIR analysis. The optimum conditions of copper sorption from paper mill wastewater onto PPy / PANI were found to be: pH=۶, contact time ۱۲ min and ۰.۴ g of sorbent in ۱۰۰ ml in wastewater. The kinetic studies showed that the sorption process was well described by the pseudo second order kinetic model. Also, Langmuir isotherm provided the best fit to the equilibrium data. Also the effect of temperature on the process was found that the temperature has positive effect on the process. Thermodynamic parameters showed that the sorption of copper onto nano fiber were feasible, spontaneous and endothermic under studied conditions.
