WebThe reactions with metal cations are pH dependent. At very low pH (<1.3), the main sorption mechanism is the reaction of phosphate ions with iron. Within the pH range of 1.3-4.3, the phosphate ions mainly create a complex with aluminium. At higher pH values (4.3-7.2), the phosphate ions are commonly in the form of hydrolysed phosphate ions. WebBelow 7.0 is acid, and above 7.0 is basic or alkaline. A pH range of 6.8 to 7.2 is termed near neutral.
