Removal of Low Concentration Phosphate in Phosphogypsum Leachate
School of Resources and Safety Engineering, Central South University, Changsha, Hunan, 410083, China
In order to find a method for removing low-concentration phosphate from phosphogypsum leachate, modified quartz sand was used as adsorbent. The effects of adsorbent dosage, phosphate concentration and adsorption time on phosphate removal efficiency were investigated. The results show that the optimum dosage of modified quartz sand was 0.024g/mL. The effluent phosphate concentration was lower than 0.023g/mL, and the phosphate removal efficiency could reach up to 98%.
