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. WebThe results showed that, with solutions 0.001M in Fe, 0.0002 to 0.001M in phosphate, and NaOH/Fe molar ratios ranging from 0 to 3 (pH 2.6 to 7.8), all precipitates were amorphous basic iron(III) phosphates without any tendency to crystallize toward strengite-type compounds for up to at least 66 months.
