摘要
等离子发射光谱(ICP-AES)已广泛应用于医学,地质,水质,环境等领域的检测。本文利用钙的主、次灵敏线同时测定盐湖卤水及盐水中各种不同含量的钙,其加标回收率在94.0%—100.8%范围内,与经典的容量法对比,数据能满足要求,样品浓度小于100mg/L时用灵敏线Ca317.9nm测定,样品浓度大于100mg/L时用次灵敏线Ca210.3nm测定。此法快速、准确,结果令人满意。
ICP-AES has been widely used in medicine,geology,water quality,environmental,and other areas of detection. This paper studies the use of calcium in primary and secondary sensitive line in salt lake and at the same time in various saline content of calcium ,plus the recovery in the scope and capacity of the classic comparison of data to meet the requirements of its deviation in the rate. This method is fast and accurate,with satisfactory results.
