本文研究了在碳酸氢钠介质中钴（Ⅱ）催化过氧化氢氧化金莲橙ＯＯ的褪色反应及其动力学条件，建立了一种高灵敏度测定酒中痕量钴（Ⅱ）的新方法．本法灵敏度为８．３４×１０－９ｇ／Ｌ，测定范围０－６μｇ／Ｌ．
In this paper, the bleaching reaction and kinetic conditions of cobalt (Ⅱ) -oxidation of nasturtium orange (OO) catalyzed by sodium bicarbonate in sodium bicarbonate medium were studied. A new method of high sensitivity determination of trace cobalt (Ⅱ) in wine was established. Sensitivity of this method is 8.34 × 10-9g / L, the determination range 0-6μg / L.
