高压消解-原子荧光光谱法测定牛初乳中硒的研究
High Pressure Digestion - Atomic Fluorescence Spectrometric Determination of Selenium in Bovine Colostrum
摘要
Abstract
Established by hydride atomic fluorescence method for the determination of selenium in bovine colostrum, investigates the methods of pretreatment and atom fluorescence instrument effects on the experimental results, and finally determine the digestion reagent6： 2： ： 1： nitrate hydrogen peroxide： ultrapure water, with high pressure digestion of bovine colostrum samples, digestion temperature 130-140C, time 2-3hours; atomic fluorescence reducing agent forl4g / L potassium borohydride, load flow solution for 5% hydrochloric acid. Get the selenium detection limit of0.1ng / ml, the relative standard deviation for0.!6%-1.61%, recovery rate range for 88%-102%.关键词
