Decolorization and mineralization of Batik wastewater through solar photocatalytic process
Wan Fadhilah, Khalik; Ho, Li Ngee; Ong, Soon-An; Wong, Yee Shian; Nik Athirah, Yusoff; Muhammad Ridwan, Fahmi (Penerbit Universiti Kebangsaan Malaysia, 2015-04-01)In this study, the photocatalytic degradation of batik wastewater in the presence of zinc oxide (ZnO) as photocatalyst was investigated. The effect of various operating parameters, such as pH of batik wastewater, catalyst ... -
Degradation of phenol through solar-photocatalytic treatment by zinc oxide in aqueous solution
Nik Athirah, Yusoff; Ong, Soon-An; Ho, Li Ngee; Wong, Yee Shian; Wan Fadhilah, Khalik (Taylor and Francis Ltd., 2015-05-08)Phenol-containing wastewater is only allowed in a very small amount either in sewage or industrial effluent due to the hazardous effect towards the environment. The objective of this study was to investigate the photocatalytic ... -
Evaluation on the molecular structure of azo dye in photocatalytic mineralization under solar light irradiation
Wan Fadhilah, Khalik; Ong, Soon-An; Ho, Li Ngee; Wong, Yee Shian; Nik Athirah, Yusoff; Muhammad Ridwan, Fahmi (Taylor and Francis Ltd., 2015-08-21)The aim of this study was to investigate the effects of number of sulphonic groups on solar photocatalytic degradation of Acid Orange 7 (AO7), Orange G (OG), New Coccine (NC), Reactive Black 5 (RB5) and Reactive Green 19 ... -
Photocatalytic activity of zinc oxide (ZnO) synthesized through different methods
Nik Athirah, Yusoff; Ho, Li Ngee; Ong, Soon-An; Wong, Yee Shian; Wan Fadhilah, Khalik (Taylor and Francis Ltd., 2016-06)Derivatives of phenol are considered as part of the persistent organic pollutants with endocrine effects persist in the environment and resist to bio-degradation which is difficult to be degraded. The objective of this ...
