这是一个铁矿石中全铁无汞盐快速测定法。矿样溶液在1NHCl条件下流经银还原器直接还原为亚铁,再用硫酸铈滴定。从对标样的分析结果看,证明本法是准确的,并且消除,汞和铬的严重污染,银还原器还可再生重复使用等优点。 This is a rapid determination method of total iron mercury-free salt in iron ore. Sample solution in 1NHCl flow through the silver reducer directly reduced to ferrous, and then titration with cerium sulfate. From the analysis of the standard sample, the proof of this law is accurate, and eliminate the serious pollution of mercury and chromium, silver restorer can also be reused and so on.
