摘要
研究了阴极铜中微量砷和锑测定断续流动氢化物原子荧光光谱法 (HGAFS) ,该法简便、快速。采用氢氧化铁一次共沉淀即可定量富集这两种待测元素 ,和基体及其它共存元素分离后不影响这两种元素的测定。样品中砷和锑的检测限均小于0 5
A simple and rapid method is described for the determination of traces amounts of As,Sb in pure cathode copper metal by spiccato flow HGAFS The two elements are coprecipitated simultaneously with ferric hydroxide and separated quantitatively from a pure cathode copper matrix and other interfering elements prior to the determination The detection limits of As and Sb in samples are less than 0 50μg g -1 The determination results of the three elements are satisfactory The precision and accuracy are good
