摘要
Abstract
In this paper,iron ore was digested by HNO3 + HF cid system,and the hydrolysate was enriched,adsorbed and eluted by polyurethane foam.And then the graphite furnace atomic absorption spectroscopy is used for the determination,and the external standard method is used for quantitative determination.The acid digestion system,the oscillation time,the frequency of preconcentration and the temperature-rising Program of Tl measurement in graphite furnace were 0.020mg/kg.The relative deviation was<5.0(n= 11).The recovery was 90%-100%after standard addition in the whole process.关键词
