Removal of phenols from the aqueous solutions based on their electrochemical polymerization on the polyaniline electrode

Phenol and 3-nitrophenol in a aqueous solution of NaCl with pH 4.0 can be polymerized on the polyaniline electrode to form polyaniline/polyphenol and polyaniline/poly(3-nitrophenol) composites, respectively, using potential cycling between −0.20 and 1.00 V (vs. SCE). Polyaniline played an important role in lowering passivation of the electrode, which made the consecutive electrochemical polymerization of phenol and 3-nitrophenol become possible. The growth of the polyaniline/polyphenol and polyaniline/poly(3-nitrophenol) films in the electrolytic process was proved by the increasing area of the cyclic voltammograms as the electrolysis proceeded. The SEM images and IR spectra of polyaniline and phenolic polymers demonstrated the formation of the phenolic polymers on the polyaniline electrode. Therefore, the removal of both phenolic compounds is based on the formation of their polymers on the polyaniline film.     

Preparation and corrosion resistance of nanostructured PVC/ZnO–polyaniline hybrid coating

ZnO–polyaniline nanocomposite with core–shell nanostructure was prepared by in situ polymerization of aniline monomer in the presence of ZnO nanoparticles. Fourier transform infrared spectroscopy, X-ray diffraction patterns, field emission scanning electron microscopy and transmission electron microscopy techniques were used to characterize the composition and structure of ZnO–polyaniline nanocomposite. d.c. electrical conductivity measurement showed that the electrical conductivity of ZnO–polyaniline nanocomposite pellets is higher than that of pristine polyaniline and ZnO nanoparticles pellets. The addition of ZnO nanoparticles causes to the increasing of polyaniline electrical conductivity. ZnO–polyaniline nanocomposite was mixed with polyvinyl chloride (PVC) through a solution mixing method and the three components PVC/ZnO–polyaniline hybrid material was applied as coating on iron coupon by the solution casting method. Corrosion protection efficiency of PVC/ZnO–polyaniline hybrid coating on iron coupons was studied by open circuit potential and Tafel techniques in 3.5% NaCl solution as corrosive environment. According to the results, PVC/ZnO–polyaniline hybrid nanocomposite coating showed dramatically increased corrosion protection effect on iron samples compared to that of uncoated iron coupon and pure polyaniline anticorrosive coating. It was found that ZnO nanoparticles improve the barrier and electrochemical anticorrosive properties of polyaniline and the addition of polyvinyl chloride increases the barrier effect of polyaniline coating.
