摘要

研究电感耦合等离子体发射光谱(ICP-OES)法测定Ap1000核电厂闭式循环水系统内的铁、铜的方法,优化了ICP-OES的仪器工作方法和分析条件,排除钼酸根、TTA、亚硝酸根基体干扰,采用标准加入法和标准曲线法,选择合适的波长与基体匹配。本方法线性范围宽,分析速度快。结果表明:所建立方法的准确性、精密度和长期稳定性均满足要求,是测定Ap1000核电厂闭式循环水系统内的铁、铜分析非常可靠的方法。
        The method of determination of iron and copper in the closed cycle water system of Ap1000 nuclear power plant by ICP-OES was studied, and the working methods and conditions of ICP-OES apparatus were optimized. To eliminate the interference of molybdate, TTA, nitrite Matrix, standard addition method and standard curve method, the suitable wavelength is chosen to match the matrix. The method has wide linear range and fast analysis speed. The results show that the accuracy, precision and long-term stability of the established method meet the requirements. It is a very reliable method to determine the iron and copper analysis in the closed circulation water system of the Ap1000 nuclear power plant.
