摘　　要：主要介绍一种无汞法SnCl_2-TiCl_3-K_2Cr_2O_7法测定铁矿石中铁的含量,这个方法避免了有汞法对环境的污染,实验精确度高,目前已列为铁矿石分析的国家标准.In this paper a new non-mercury method which uses SnCl 2-TiCl 3-K 2Cr 2O 7 to measure the amount of iron in iron ore is introduced . The means avoids enviromental pollution by mercury method and the accuracy is high .By now it has ranked a national standard to analyse iron ore .
