| dc.description.abstract | In this study, adsorption of Brilliant Green (BG) dye using natural clay as adsorbent was being modified by inserting photocatalyst for colour removal and degradation. A coating formulation of titanium oxide, bentonite and acrylic polymer was prepared using a coating method which will act as thin adsorbent layer. The adsorbent layer was investigated to obtain the optimum ratio for adsorption process. It was found that the best ratio was 0.2 g of titanium oxide, 0.3 g of bentonite and 1.5 g of acrylic polymer where 97% of dye removal had been achieved in 5 hours. This adsorbent coating with the optimum ratio was further characterized and the performance evaluation was performed. Characterization of the adsorbent evaluated by SEM, FTIR, DRS and Zeta Potential. Furthermore, performance of the adsorbent was tested by varying the initial concentration (50-200 mg/L) of dye, solution pH (3- 11) and temperature (30 oC-70 oC). The obtained equilibrium data for BG dye was best fitted by Freundlich model. Meanwhile, the kinetics data was best represented by the pseudo second-order model. The result revealed that this adsorbent coating has the potential for future wastewater technology. | en_US |
