This study investigated the adsorption of PO 4 3− onto encapsulated nanoscale zero-valent iron (nZVI). At initial PO 4 3- : 10 mg · L −1 , the optimum condition was initial pH: 6.5, nZVI dosage: 20 g · L −1 , stirring-rate: 100 rpm, and time: 30 min, achieving PO 4 3− removal of 42%. The effect of p...
