钙制剂中铝含量分析方法
技术领域
本发明涉及一种化学分析方法,特别是涉及一种钙制剂中测定微量铝的分析方法。
背景技术
荧光分光光度法是对荧光物质进行定性和定量的有效方法,在药物分析中主要用于微量或痕量物质的定性或定量测定。具备以下特点:(1) 灵敏度高,光分析的最大特点是灵敏度高,通常比紫外可见光度计高出2—3个数量级;2) 选择性强,荧光分析法的光谱比较简单,特征性强;(3) 提供较多的物理参数,可提供激发光谱、发射光谱和三维光谱以及荧光强度、荧光效率、荧光寿命、荧光成像等多种物理参数;(4) 操作方法简便。钙是人体内最普遍的元素之一,对于人体代谢、细胞功能、神经系统运作、 蛋白和激素合成等起到至关重要的作用,钙制剂已经成为药品和保健品市场重要品种之一。铝并非人体需要的微量元素,属于低毒性的金属元素,不会引起急性中毒,但进入细胞的铝可与多种蛋白质、酶、三磷酸腺苷等人体重要物质结合,影响体内的多种生化反应。钙制剂中残留铝含量超标,危害身体健康,加强药品质量检验检测意义重大。
