摘要
研究发现在酸性介质中,Mo(VI)对过氧化氢氧化酸性铬蓝k褪色的反应有较强的阻抑作用,据此建立了阻抑动力学光度法测定痕量钼的方法。方法线性范围为0～3.4μg/25ml,检出限为3.1×10^(-10)g/ml。方法已用于蔬菜中钼的测定,结果满意。
It was reported that trace amounts of Mo(VI) could inhibit the decoloring reaction of acid chrome blue k by hydrogenperoxide in acidic condition.The linear range of the method was 0～3.4μg/25ml for Mo(VI), with detection limit of 3.1×10g/ml. The proposed method has been applied to determination of trace molybdenum in vegetables with recovery of 97%～102%.
