摘要: The adsorptive removal of total dissolved solids by activated coal using response surface methodology was investigated. A four-variable central composite experimental design applied to correlate the adsorption variables (effluent pH, adsorbent dosage, contact time, and temperature). were optimized based on from fibre cement industry effluent. Three-dimensional plots generated estimate effect combinations independent efficiency. results model validation gave yield 96.2%, predicted 96.5% obtained at effluent pH 6.27, dosage 27.60 mg L−1, time 48.00 min, temperature 31.00 °C. good agreement found between observed values supports suitability predict treatment.
