摘要
研究了在酸性介质下，氟化钠为掩蔽剂，用高碘酸钠来氧化对氨基苯磺酸，用催化动力学测定痕量锰的新方法，该方法检出下限为４×１０－８ｇ／ｍＬ，线性范围为０．０５～０．６μｇ／ｍＬ，可应用于铝板中锰含量的测定。
A new method to measure trace manganese by catalytic dynamics,through the oxidation of sulfanilic acid by sodium iodate and taking sodium-fluoride for a masking agent in acid materials,is studied,The method whle lower limit of measure is 4×10-8g/mL and linear range 0.05￣0.6μg/mL,can be used for the measurement of manganese content in aluminum plates.
