摘要
本试验采用HCS-KR200高频红外碳硫分析仪测定磷矿石中硫含量。将样品于105℃烘干,称取样品0.0400g,加入0.400g矿石专用助熔剂(1号),搅拌均匀,再加入0.5g纯铁助熔剂,1.5g KRWL-1助熔剂,到碳硫分析仪上测定。该方法操作流程简单,结果稳定,准确度高,快捷。方法精度达0.0001%-5%。满足磷矿石中硫分析质量要求。
In this paper,the sulfur content in phosphate rock is determined by HCS-KR200 high frequency infrared carbon sulfur analyzer.Process：Dry the sample at 105 ℃,weigh 0.0400 g sample,add 0.400 g ore special flux（No.1）,stir,then add 0.5g iron flux,1.5g KRWL-1 flux,and determine by sulfur analyzer.The method is simple,stable,accurate and fast.The accuracy of the method is 0.0001%-5%,meeting the quality requirements of sulfur analysis in phosphate rock.
