| 摘 要： | 通过对铜精矿及铜矿石中大量铜离子等多种金属离子对原子荧光光谱法测定砷干扰的消除,建立一种适合的溶样方法,选择了最佳的分析条件,克服了普通原子荧光法溶解样品的不足,本方法测定砷的检出限为1μg/g。本方法测定了3个国家一级标准物质中砷的含量,测定值与推荐值吻合,确定方法适合铜含量比较高的样品中砷含量的测定。

| Abstract: | By removing the disturbance of determined arsenic with the atomic fluorescent spectrometry,which by copper ion and other metal ion in copper concentrate and copper ore,to build a suited dissolution method,and to choose the optimization condition,to overcome the shortage of general atomic fluorescent spectrometry dissolved the sample.The detection limit of the method is 1μg/g.This method is applied to three national standard samples(level one) to detect the content of arsenic.The detected values and recommended ones are consistent.Therefore,the method is feasible to test the content of arsenic in high copper concentrate samples. |
