研究了痕量锰氧化萘酚绿褪色和生色反应及其动力学条件 ,并应用 570和 71 0 nm双波长组合 ,建立了测定痕量锰的新方法。测定线性范围为 8～ 2 2 .5μg·ml- 1 ,检出限为 6.8μg·ml- 1 。该方法用于中蒙药中痕量锰的测定 ,获得满意结果。
The fading and chromogenic reaction and kinetic conditions of trace amounts of manganese oxide naphthenate green were studied. A new method for the determination of trace manganese was developed by using 570 and 71 0 nm dual wavelength combinations. The linear range was 8 ~ 22.5μg · ml-1 with the detection limit of 6.8μg · ml-1. The method is applied to the determination of trace manganese in the Chinese traditional Mongolian medicine and obtain satisfactory results.
