AN-H-107
Determination of ferrous ion content in hydrometallurgical leach liquors
Tóm tắt
A measured amount of acidic hydrometallurgical leach liquor is further acidified with sulfuric acid, prior to being titrated with standard potassium dichromate solution to an exothermic endpoint. Thus, 1 mol K2Cr207 ≡ 6 mol Fe2+.
