| 摘 要： | 矿石样品用磷酸、盐酸和高氯酸的混合酸分解,然后利用高氯酸加热至冒烟时呈现的强氧化性,将钒、锰等氧化至高价,掩蔽其他干扰元素,以N-苯代邻氨基苯甲酸作指示剂,以硫酸亚铁铵标准溶液滴定试液中的钒和锰.方法简便、快速,V2O5和Mn的回收率分别为99.32%～100.56%和99.66%～100.71%,相对标准偏差分别为3.07%～5.34%和4.54%～5.70%.

| Abstract: | The ore sample was decomposed by mixed acid of phosphoric acid,hydrochloric acid and perchloric acid.The lower valence manganese and vanadium in ore are oxidized at suitable temperature.After screening interferential elements,the manganese and vanadium were determined by titration using N-phenyl anthranllic acid as indicator and ammonium ferrous sulfate as titrant.The method was easy and quike,the recovery rate is 99.80%~100.20% for Mn,99.82%~100.25% for V2O5.The relative standard deviation is 3.07%~5.34% f... |
