Comparison between the photocatalytic degradation of single and binary azo dyes in TiO2 suspensions under solar light irradiation
(IWA Publishing, 2015-12)Textile industries discharge a large quantity of colored wastewater which is harmful to the ecosystem. In this study, two kinds of dyes were investigated: the mono azo Acid Orange 7 (AO7) and diazo Reactive Green 19 (RG19). ... -
Degradation of cationic and anionic dyes in coagulation-flocculation process using bi-functionalized silica hybrid with aluminum-ferric as auxiliary agent
(Royal Society of Chemistry, 2015)Cationic dye (methylene blue) and anionic dye (methyl orange) degradation in the coagulation process was demonstrated. The key material was a natural coagulant-laterite soil dominated by a silica component, while aluminum-ferric ... -
Performance evaluation of treated adsorbents derived from agricultural waste towards adsortion of azo dyes
(Universiti Malaysia Perlis (UniMAP)School of Environmental Engineering, 2011-04)Wastewaters generated from the industries contain large amounts of azo dyes which, owning to their non-biodegradability, toxicity and potential carcinogenic nature, constitute a major threat to the surrounding ecosystem. ... -
Study on Photocatalytic mineralization of various azo dyes under solar light irradiation
(Universiti Malaysia Perlis (UniMAP)School of Environmental Engineering, 2014)Azo dyes represented by azo chromophores (-N=N-) are the largest class of dyes used in many industries especially textile industries. Other chemicals that mutagenic or toxic to the environment and human life will present ...
