岩石中猛钛的定量分析,以往一般都是在同一份除去二氧化硅的滤液中,取两份试液,分别用过碘酸钾法和过氧化氢法进行比色测定。上述方法从准确度上讲,虽然都具有一定的可靠性,但多年来一直未能摆脱多次分液和单独测定的烦琐操作。特别是锰钛的测定,在一般的岩石分析中,往往同时要求,而两者的分析又均须在硫和磷酸的存在下进行,故不仅 Rock quantitative analysis of fierce titanium, in the past are usually in the same filtrate to remove silica, take two test solution, respectively, by potassium periodate method and hydrogen peroxide method for colorimetric determination. The accuracy of the above method, although with some reliability, has not been able to get rid of the cumbersome operation of multiple dispensing and individual determination for many years. In particular, the determination of manganese and titanium, rock analysis in the general are often required at the same time, both the analysis must be carried out in the presence of sulfur and phosphoric acid, it is not only
