一种用于人发中微量元素铬测定的新消化方法
摘要
本文用原子吸收分光光度法测试人发中微量元素铬的含量
用1:1的硝酸
在高压消化罐中消化处理发样
测试结果
比之用其他化学方法消化发样
测试精度高
回收率好
一般在96%~107%.且节省试剂
操作简单
是目前较理想的样品消化方法.
Abstract
Atomic aboerption spectro-photometer was used to determine the Chromium in human’s hair with a new digestion method in which the human’s hair was digested with 1:1 HNO3 in a high pressure digestion pot. With this new method a good result was obtained
a better collection ratio of chromium within 96%-107% was got and the reagent can be saved.
