铜精矿中总铁量的测定,据资料介绍,多以盐酸、硝酸和硫酸溶解样品,使用汞盐和铬盐,费时较长。为此,改用高氯酸溶解样品,用锌粉还原三价铁为二价铁,铜还原为金属铜,以铈盐滴定。方法简便、结果准确,因不用氨水沉淀分离铁,提高了分析速度, Determination of total iron content in copper concentrate, according to the information introduced, and more to hydrochloric acid, nitric acid and sulfuric acid to dissolve the sample, the use of mercury salts and chromium salts, time-consuming. To this end, instead of using perchloric acid to dissolve the sample, reducing iron with ferric iron to ferrous iron, copper reduction to metallic copper, titration with cerium. The method is simple and the result is accurate. Because iron is not precipitated by ammonia precipitation and the analysis speed is increased,
