摘要
研究了在ＮＨ３－ＮＨ４Ｃｌ介质中，钼催化过氧化氢氧化偶氮胂Ⅲ的褪色反应及其动力学条件，建立了一种高灵敏度测定痕量钼的新方法，可测定０．０２～０．９０μｇ／２５ｍＬ范围内的钼，方法检出限为１．３×１０－１０ｇ／２５ｍＬ．．
A method has been studied for determination of trace amount molybdenum Which is used to catalyze the discoloring reaction of hydrogen perooxide oxidizing Arsenazo Ⅲ in NH 3 NH 4Cl medium. The kinetic conditions have been studied.The method can be used to determine molybdenum in steel and water with satisfactory results.
