Studying the destruction of pollutant in the presence of photocatalysts based on MWCNTs with controlled values of TiO2 nanoparticles

Abstract The main goal of the present research is synthesis new photocatalysts to reduce amount organic pollutants in aquatic environments. For this purpose, TiO 2 nanoparticles synthesized samples containing MWCNTs controlled synthesize two types named as MCT#1 and MCT#2. Samples characterizing using XRD reveal that have a combined phase rutile anatase. So both photocatalysts, percentage anatase higher than rutile. analysis degradation rate demonstrates intensification level MCT#2 compared leads enhancement photocatalytic activity Design experiment results shows destruction MO affected by irradiation time pH. Based on ANOVA study, it observed factors significant effect reducing concentration. Analyzing based Duncan's multiple range test at α = 0.05 confirm all studied levels parameters logical influence destruction. Meanwhile, can be deducted most least pH 7 3, respectively.
