Enzymatic Removal Of Sulfonated Azo Dyes From Synthetic Textile Effluents Using Soybean Peroxidase, Temidayo Oyelere
Enzymatic Removal Of Sulfonated Azo Dyes From Synthetic Textile Effluents Using Soybean Peroxidase, Temidayo Oyelere
Electronic Theses and Dissertations
The textile industry and other colour-oriented industries utilize azo dyes in extensive amounts. Dye effluents are recalcitrant to natural biodegradation, hence, causing toxic effects on the environment. Physiochemical treatment generates sludge which requires secondary disposal; advanced oxidation processes (AOPs) are cost and energy intensive; biological methods like anaerobic treatment via bacteria generate aromatic amines which are mutagenic and carcinogenic. A promising alternative that has shown great success in the treatment of wastewater is the enzymatic method. This thesis reports the enzymatic degradation of Reactive Black 5 (RB5), Acid Orange 7 (AO7), and Acid Orange 20 (AO20) from synthetic textile effluents …
