Adsorptive removal of phosphate from aqueous solutions

The phosphate adsorption on the tailings tended to decrease with an increase of pH. A phosphate desorbability of approximately 13-14% was observed, and this low desorbability likely resulted from a strong bonding between the adsorbed PO (4) (3-)and iron oxides in the tailings. Column flow-through tests using both synthetic phosphate solution
