摘　　要：目的建立珍珠明目滴眼液中钙元素残留量的测定方法。方法采用原子吸收分光光度法（火焰法）。结果钙元素在0.0~6.0μg.mL-1范围内与其422.7nm处的吸光度成良好线性关系,钙检出限为0.001μg.mL-1,定量限为0.003μg.mL-1。结论该方法具有灵敏、简便、快速、准确、重复性好,专属性强,可作为珍珠明目滴眼液中钙元素残留量测定方法。Objective To find a new method for determining residual calcium in Zhenzhu Mingmu Eye Drops.Methods Atomic absorption spectrometry（flame AAS） was used.Results There was a good linear relationship between absorbance A（in 422.7nm） and the calcium in the range of 0.0~6.0μg·mL-1.The limit of detection for calcium was 0.001μg·mL-1,and limit of determination for calcium was 0.003μg·mL-1. Conclusions This method is sensitive, simple, fast, accurate, specific and good repeatability. It can be used to determine residual calcium in Zhezhu Mingmu Eye Drops.
