Abstract
Phosphate pollution is a major concern for soil and water management. In the present study Sapindus emarginatus seed powder was used to remove phosphate. The parameters such as initial concentration, contact time, dosage, pH and temperature were optimized. All experiments were done at room temperature except temperature studies. The Langmuir adsorption capacity of Sapindus emarginatus was found to be 6.765 mg/g. The kinetic data of phosphate adsorption was fitted well with the pseudo second order model. With the increase in temperature the phosphate removal was decreased.
