Influence of Some Preparation Parameters on The Efficiency of Activated Carbons Prepared from Teak Wood Shavings (Tectona Grandis) and Coconut Shells (Cocos Nucifera) for The Treatment of Industrial Wastewater

In this work, we valorized two wastes of plant origin in activated carbon (AC) by chemical activation, with a view to their use for the elimination industrial dyes and artisanal dyeing simulated methylene blue iodine water. These are coconut shells (Coco nucifera) teak wood chips (Tectona grandis). For preparation based on residues, activation was carried out citric acid extracts lemon juice (Citrus aurantiifolia) then compared that phosphoric hydroxide potassium. from residue, activating agent used is potassium hydroxide. The results obtained show microporous mesoporous an number between 338.9 487.9 mg/g, 369.2 447.2 mg/g more pronounced post-treatment residual acidity than juice. test conditions (the impregnation ratio, duration, carbonization temperature) made it possible prepare six carbons residue. time does not have significant effect adsorption efficiency although considerable efficiency. kinetics these materials second order isotherm Langmuir type Freundlich model; characteristic wide distribution microporosity well-developed mesoporosity. can therefore be treatment wastewater, particular removal dyeing.
