Abstract
The photocatalytic degradation of basic blue 9 was investigated in aqueous solution containing CoS/nanoAlMCM-41 photocatalyst under visible light. The catalyst is characterized by X-ray diffraction (XRD), UV–Vis diffused reflectance spectra (UV–Vis DRS) and scanning electron microscopy (SEM) techniques. The effect of CoS, nanoAlMCM-41 support and different weight percentage of CoS over the support on the photocatalytic degradation and influence of parameters such as CoS loading, catalyst a mount, pH and initial concentration of basic blue 9 on degradation are evaluated. CoS/nanoAlMCM-41 composite (17 wt%) is found to be optimum. The degradation reaction follows pseudo-first order kinetics. The effect of dosage of photocatalyst was studied in the range 0.04–1.2 g/L. It was seen that 0.8 g/L of photocatalyst is an optimum value for the dosage of photocatalyst. The degradation efficiency was decreased in dye concentration above 3.2 ppm for basic blue 9 dye. In the best conditions, the degradation efficiency was obtained 0.32 ppm for basic blue 9 dye.
