【摘要】 基于在硫酸介质中 ,肼与罗丹明 6G反应 ,使其荧光增强 ,建立了一种荧光法测定痕量肼的新方法。该方法线性范围 2 0～ 1 4 0 μg L ,检出限为0 62 μg L。可用于环境水样中肼含量的测定 ,并进行了回收实验 ,回收率为97%～ 1 0 7%。更多还原

【Abstract】 A new fluorimetric method was proposed for the determination of trace hydrazine. The method was based on the reaction of hydrazine with Rhodamine 6G in sulfuric acid medium. The detection limit for hydrazine was 0.62 μg/L. The linear range of the determination was 2.0～14.0 μg/L. The method was used to determine hydrazine in environmental water samples.更多还原
