摘要
试样经酸溶解后,以磷酸-高氯酸混合酸(4+1)或(9+1)氧化至冒烟.在硫酸、磷酸介质中,用高碘酸钾将锰氧化到七价,测其吸光度.
It is proposed that more phosphoric acid should be added during the oxidation of manganese(Ⅱ) by KIO4, especially for alloys of high chromium contents. It is also found that the amount of perchloric acid used should be limited to 2ml. It is proved that the method is more favorable by this modification.
