Abstract


The combination of adsorption and photoelectrocatalytic degradation system for Remazol Yellow FG decolorization has been studied. The adsorption of Remazol Yellow FG was carried out using alumina and silica, which was activated using H2SO4 1 M and NaOH 1 M. The adsorption results at optimum pH were then used for photoelectrocatalytic process. Photoelectrocatalytic degradation cell was built by electrode Ti/TiO2 as a cathode and Ti/TiO2-PbO as an anode. Material characterizations were performed by UV-Vis Spectrophotometers, X-Ray Diffraction (XRD), and Fourier Transform Infra-Red (FTIR). Activation of the adsorbent can increase Remazol Yellow FG adsorption on alumina base and silica acid that were reached 99.500% and 81.631%, respectively. The optimum condition of Remazol Yellow FG 6 adsorption by alumina acid was at pH 3, alumina base were at pH 4 and pH 5, and silica base were at pH 6 and pH 10. Degradation of Remazol Yellow FG using TiO2-PbO electrode was 72.756% at potential cells of 7.5 Volts for 10 minutes. The combination of adsorption and photoelectrocatalytic degradation can decrease the concentration of Remazol Yellow FG achieved 99.705%
