(a) UV–Visible spectra of Congo red (CR) at different concentrations with time intervals. (b) Removal percentage of CR within 90 min due to adsorption activity of rGO and rGO-P composite. (c) Removal percentage of CR by rGO and rGO-P nanocomposite as a function of time under UV irradiation. (d) Variation of CR removal (%) with time at different solution pH i.e. 3.0, 5.0, 7.0 and 9.0.
