| 摘 要： | 应用高频燃烧-红外碳硫吸收法测定含铜烧结物中的高含量硫。对样品称样量、助熔剂的种类、加入顺序、用量等测定条件进行研究。由于样品含硫量的不同,根据矿石标准样品中含硫量的比例关系确定具体的称样量。以纯铁屑和钨粒作助熔剂,高温燃烧分解试样,红外检测可定量测定含铜烧结物样品中含量为1%~23%的硫。方法加标回收率为94%~113%,相对标准偏差(RSD,n=6)小于2%。与经典的硫酸钡重量法对比,相对误差小于4%。建立的方法解决了大宗含铜烧结物中硫快速、准确测定的问题,已应用于实际的日常检验工作。 |
| 关 键 词： | 高含量硫 含铜烧结物料 高频燃烧-红外碳硫吸收仪 |

| Abstract: | A method for the determination of high content sulfur in copper sinters by high frequency-infrared carbon-sulfur spectrometry was presented in this paper.The analytical conditions such as sample weighting amount,flux types,loading sequence and quantity,etc.have been tested.60-120 mg of sample mixed with 0.4 g of pure iron filings and 1.3 g of tungsten pellets in a ceramic crucible was melt by a high frequency furnace and the carbon and sulfur in the sample was then determined.The concentrations of sulfur de... |
| Keywords: | high content sulfur copper sinter high frequency-infrared carbon-sulfur absorption spectrometer |
