摘要
锡铜矿石中硫的分析方法有很多,研究了电感耦合等离子体发射光谱法、高频红外碳硫仪分析法和燃烧-碘量法三种不同分析方法测定锡铜矿石中硫的精密度、准确度、检测限,三种方法的精密度和准确度均较好;通过对比检测限得出:高频红外碳硫仪分析法适合含硫量为0.001%～20%的锡铜矿石的分析;电感耦合等离子体发射光谱法适合含硫量为0.001%～10%的锡铜矿石的分析;燃烧-碘量法适合含硫量较高的锡铜矿石的分析.
Abstract
There are many methods for analyzing sulfur in tin copper ore.This article studies the precision,accuracy,and detection limit of sulfur in tin copper ore using three different analysis methods:inductively coupled plasma emission spectroscopy,high-frequency infrared carbon sulfur analyzer analysis,and combustion iodine measurement.The precision and accuracy of the three methods are all good;Through experimental comparison of detection limits,it is concluded that the high-frequency infrared carbon sulfur analyzer analysis method is suitable for the analysis of tin copper ores with a sulfur content of 0.001%-20%;Inductively coupled plasma emission spectroscopy is suitable for the analysis of tin copper ores with sulfur content ranging from 0.001%to 10%;The combustion iodine method is suitable for the analysis of tin copper ores with high sulfur content.
