摘要
探讨了通过配伍不同组分体系的盐酸、硝酸、浓硫酸混合溶液,并且适当添加双氧水、EDTA、离子液体等试剂来对富铅食品进行快速消解,提取样品中的铅,将得到的数据与国标测定方法(原子吸收光谱方法)相比较,计算其回收率.建立了一种重金属铅的新颖高效快速前处理方法.
In the study,different proportions of hydrochloric acid,a nitric acid,strong sulfuric acid mixture,and an appropriately-added hydrogen peroxide,EDTA,ionic liquid,etc.to rich lead food reagent were confected to make a fast digestion and extract the samples of the lead;with GB data obtained in the food,the calculation method was then compared and the lead recovery was calculated.A novel and high performance rapid sample pretreatment method of heavy metal lead was suggested in this paper.
