Dye water pollution is the common problem in industries, especially textile industry. The conventional biological waste water treatment is not efficient enough to fully degrade coloured dye waste water stream. However, dye pollutants are able to be more efficiently broken down by light sources. Photocatalytic degradation of rhodamine B (RhB), methylene blue (MB) and methyl orange (MO) under sunlight by self-made photoreactor were studied. Graphitic carbon nitride (g-C3N4) with band gap energy of 2.75 eV is used as the photocatalyst. It is a visible light activated photocatalyst synthesized at temperature of 500 °C for 3 hours in muffle furnace. The degradation rate of different dye was investigated and the effects of flow rate were studied. RhB dye showed the highest potential to be degraded under sunlight illumination. With the use of self-made photoreactor model at highest flow rate, the degradation efficiency was found to be 100% under 2 hours of sunlight illumination. The modifications on reactor successfully increase the sunlight concentration and improved the rate of degradation. [ABSTRACT FROM AUTHOR] |
