痕量碲的测定,一般采用原子吸收光度法和原子发射光谱法等。本文研究了硫酸介质中痕量碲(Ⅳ)催化高碘酸钾、过氧化氢和中性红之间的褪色反应及动力学条件,建立了测定痕量碲(Ⅳ)的新方法。
Determination of trace amounts of tellurium, the general method of atomic absorption spectrometry and atomic emission spectrometry. In this paper, the fading reaction and kinetic conditions of potassium telluride (Ⅳ) catalyzed by potassium perchlorate, hydrogen peroxide and neutral red in sulfuric acid medium were studied. A new method for the determination of trace tellurium (Ⅳ) was established.
