Buyer’s Notes
Choosing the grade. The heptahydrate holds about 19.7-19.8% ferrous iron on this report. Check the ferric iron figure too, since oxidised material reduces effectiveness for chromate reduction and phosphate removal.
What to check on the spec sheet. Purity, ferrous iron (19.74% min), ferric iron (0.25% max), free acid, moisture and pH of a 5% solution. Colour should be light green; brown crusts show oxidation.
Handling and storage. Oxidises on prolonged air exposure, so keep bags closed in a cool, dry store, and use older stock first. Dust is irritating; wear gloves and a mask.
Where it is used. Flocculant and phosphate removal in wastewater, micronutrient supplement, iron oxide pigment feedstock, and chromate reducer in cement.
