高频燃烧-红外碳硫吸收仪快速测定含铜烧结物料中的高含量硫
Rapid Determination of High Content Sulfur in Copper Sinters by High Frequency-Infrared Carbon-Sulfur Absorption Spectrometer
摘要
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 determined by this method range from 1％ -23％. The recovery is between 94％ and 113％ , and RSD is less than 2％. Comparing with the routine gravimetric method of BaSO4, this method provides more reasonable results for copper sinters with RE less than 4％. This method has been applied to practical sample analysis for rapid and accurate determination of the high content sulfur in copper sinters.关键词
