钙的测定在许多科学领域都非常重要，一种好的分析方法必须具备应用范围较广、样品前处理比较简便、处理后干扰较少或易于消除、准确度和精密度好等优点。通常像血、尿、体液以及水和饮料等试样经适当稀释后，可用原子吸收光谱法直接测定；生物组织、食品、饲料等试样则需... The determination of calcium is very important in many scientific fields. A good analytical method must have the advantages of wide range of applications, simple sample preparation, less or eliminated interference after treatment, and good accuracy and precision. Usually like blood, urine, body fluids and water and beverages and other samples after appropriate dilution, the direct determination by atomic absorption spectrometry; biological tissue, food, feed and other samples are required ...
