| Abstract: | A method for the determination of arsenic,antimony and bismuth in copper ores by hydride generation-atomic fluorescence spectrometry was developed.The sample was dissolved by aqua regia and copper was then effectively separated by using Fe3+ as coprecipitation agent in ammonium hydroxide solution.Arsenic,antimony and bismuth in the sample solution were determined by hydride generation-atomic fluorescence spectrometry.The detection limits of the method are 0.19 μg/g for arsenic,0.052 μg/g for antimony and 0.049 μg/g for bismuth.The precisions(RSD,n=10) of the method are 5.87% for arsenic,7.58% for antimony and 2.42% for bismuth. |
