火焰原子吸收法测定人发中钙、镁、铜、铁、锌含量
Determination of Ca、Mg、Cu、Fe and Zn in Human Hair by FAAS
【摘要】 以硝酸-双氧水为混合溶剂,湿法溶解发样,考查了人发中共存离子的干扰情况,并对钙在空气-乙炔火焰中电离,提出了抑制的方法。人发5种元素回收率分别为钙100.7%,镁102.0%,铜104.0%,铁102.0%,锌103.0%。
【Abstract】 HNO 3-H 2O 2 as the selvent to resolve the samples, the glasswares are put in the dilute HNO 3 for cetrain time before use. The interference of coexisting ions was studied and the eliminating method was also proposed for electro-disso ciation of Ca in air-acetylene. The recoveries of the method for the determination of 5 metal elements in human hair are Ca: 100.7 %, Mg: 102.0 %, Cu: 104.0 %, Fe: 102.0 % and Zn: 103.6 % respectively.
