Photocatalytic degradation of congo red dye based on titanium dioxide using solar and UV lamp / Nurul Syuhaibah Harun

The textile industries produce large volume of wastewater and contain chemical associated with the dyeing process. Azo dyes is one of the chemical used in dyeing process which consist of azo structure that have biodegradation resistance, thus the biological treatment method is unsuitable to degr...
