Evaluation on the photocatalytic degradation activity of Reactive Blue 4 using pure anatase nano-TiO2

Disposal of dye wastewater into water streams without treatment endangers human and marine lives. This work focused on the second largest class of textile dyes after azo dyes due to its high resistivity to biodegradation and high toxicity. The photocatalytic degradation of Reactive Blue 4 (RB4), an...
