Figure 3
Normalized absorption spectra of R6G (1 × 10-5 mol dm−3; exposure time: 210 min; sunlight intensity: 500–600 W/m2); sun blank 1: sunlight irradiation to R6G without HDPE; dark blank 2 : dark adsorption of R6G over HDPE beads in the dark; sun blank 3: sunlight irradiation of R6G over HDPE beads; dark adsorption 1: adsorption of R6G over TiO2-bound HDPE beads in the dark; dark adsorption 2: adsorption of R6G over Au/TiO2-bound HDPE beads in the dark.
