摘　　要：用原子吸收光谱法测定高磷高钙液体复合肥中的钙.结果表明:在设定好测试条件、步骤、抗干扰方法的前提下,此法能准确快速地测定该肥料中钙的含量.进而用多种方法进行比较,表明原子吸收光谱法是测定高磷高钙液体复混肥中复杂形态钙含量的最佳方法.Ca content in the high P/Ca liquid compound fertilizer cannot be accurately determined by current standard methods, because of the Ca being the complex state. Based on the comparative study of several analytical methods, atomic absorption spectrometry was proved to be a fast and accurate method to determine the Ca content in high P/Ca liquid fertilizers with proper setup and the instrumental conditions including anti-interference method.
