【摘要】 介绍矿石中测定铁的方法,主要是用HCI-NH₄F-HClO₄混酸快速溶样,用Zn粉还原,K₂Cr₂O₇溶液滴定。其应用范围宽,RDS在0.068～0.080之间,结果满意。更多还原

【Abstract】 The paper introduces the method for quick determination of the iron content in the ores, in which the iron was quickly dissolved in the mixed acid of HCI-NH4F-HClO4 and reduced by adding into the zinc powder subsequently, the iron content in the ores was quickly determined with K2Cr2O7 solution.This method has wide uses with satisfied test results. RDS is between 0.060 - 0.080.更多还原
