Thermo-Kinetics Studies of Dye Removal with Kaolin from Tectona grandis and Indigo Dye Effluents

Synthesis of high surface area mesoporous ZnCl2–activated cocoa (Theobroma cacao L) leaves biochar derived via pyrolysis for crystal violet dye removal

“…Thus, CV dye removal is mandatory before discharging CV-contaminated wastewater into water body to circumvent possible health hazard associated with it. There are many methods to treat dye-house effluent and the main ones can be classified as chemical oxidation [ 11 ], ozonation [ 12 ], electrochemical [ 13 ], coagulation/flocculation [ 14 ], membrane filtration [ 15 ], photo-degradation [ 16 ], biological [ 17 ], precipitation [ 18 ] and adsorption process [ 19 , 20 , 21 ]. Among these methods, adsorption is preferred because of its simplicity and high removal efficiency.…”
