Application:
Ammonium Iron(III) Sulfate Dodecahydrate (CAS: 7783-83-7) is used as an analytical reagent and as an indicator in the determination of halogens. Ammonium Ferric Sulfate indicator method should be carried out in dilute nitric acid solution, because iron ions can form ferric hydroxide precipitation in neutral or alkaline medium. Ammonium Iron(III) Sulfate Dodecahydrateis a kind of nitrogen fertilizer which can provide N for NPK and mostly used for agriculture. Besides providing the element of nitrogen, it can also provide the element of sulphate for crops, pastures and other plants. Because of its fast release and quick acting, ammonium sulfate is much better than other nitrogen furtillizers such as urea, ammonium bicarbonate, ammonium chloride and ammonium nitrat. Mainly used for making compound fertilizer, potassium sulfate, ammonium chloride, ammonium sulfate, etc, can also be used for rare earths mining.
