| Abstract: | To find out the ways of determining the content of As and Sb and Hg and Ge in lead zinc primary mineral,lead concentrate,zinc concentrate with hydride generation-atomic fluorescence spectrometry(HGAFS),inquired into trying the resolution of samples,instrument work parameter and carry discharge to shield density etc of the amount of current of KBH4 of excellent turn a choice,measure and together measure after list and the contrast of national standard material experiment,give satisfaction as a result.The average value of the rate of recovery was As 92.2%,Sb 104.3%;Hg 102.6%.And RSD(n=6) the average value of As,Sb and Hg was 1.08% and 1.2% and 3.4%. |
