Copper Removal From Paper Mill Wastewater Using Polymer Nanofiber

This research work aims to investigate the sorption characteristic of synthesized polypyrrole/ polyaniline (PPy/PANI) nanofiber for Cu(II) removal from paper mill wastewater. The sorption is carried out by a 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=6, contact time 12min and 0.4 g of sorbent in 100ml 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 a positive effect on the process. Thermodynamic parameters showed that the sorption of copper onto nanofiber was feasible, spontaneous, and endothermic understudied conditions.
