The Effect Of Dopant Variation On Photocatalytic Degradation Of Wastewater Effluent From Ginchi Paper Factory Using Cu-Nio Nanoparticle Treated With Polyaniline

Abstract

This research is to investigate the effect of dopant variation on the photo catalytic treatment of wastewater effluent from Ginchi paper Factory using Cu-NiO nanoparticle modified with polyaniline molecules. Cu-NiO/PANI (3,12,21,30) nanocomposite was prepared via the sol-gel technique following in situ oxidative polymerization of polyaniline (PANI). XRD, SEM, UV-Vis, and FT-IR spectroscopy were employed to study the crystal size, surface morphology, bandgap energy, and bond structure of synthesized nanocomposites. Accordingly, the mean crystallite size of the nanocomposite determined from XRD was 17.33 nm. Photocatalytic degradation of Methylene Blue (MB) dye-containing wastewater sample using as-synthesized photo catalysts was studied under visible light irradiation. The highest degradation efficiency was recorded by Cu-NiO/PANI12 nanocomposites with 98.51% in 120 min irradiation time. The optimal conditions for photocatalytic degradation are as follows: the concentration of methylene blue (40ppm), pH (6), and the catalyst load (0.14 g) under visible light with an irradiation time of 120 min. The prepared material proves to be a potential photo catalyst for the degradation of dye polluted water.
