摘要: Abstract Moringa oleifera seed extract was confirmed as a feasible coagulant in removing surfactants from aqueous effluents. Amongst them, long-chain anionic detergents such Polyoxyethylene (3.5) sodium lauryl ether sulfate (SLES) selected model compound for evaluating the coagulation response. The system coagulant–detergent stable with different temperatures and pH, efficiency very promising. M. an effective since it capable to reach up 0.245 mg mg −1 capacity according Gu–Zhu model. Design of experiments presented optimum combination dosage initial surfactant concentration 234 mg L 76 mg L , respectively.
