Abstract:
      Determination methods of Toxic Elements As, Cd, Cr, Pb, Sb in Southern Red Agate by ICP-AES were investigated. After the selection of analysis lines and the study of the matrix interference, the best analytical conditions were determined, and the similarities and differences between the standard curve method and the standard addition method were compared. The corresponding determination results and recovery rates of As, Cd, Cr, Pb, Sb elements between the two methods are close. For Mg element determination, the standard addition method has higher recovery rate than standard curve method. Recovery rates of As, Cd, Cr, Pb, Sb elements obtained by standard curve method ranged from 93.6% ~ 103%, and RSDs (n = 6) were less than 10%. Correspondingly, Recovery rates of As, Cd, Cr, Pb, Sb elements obtained by standard addition method ranged from 90.2% ~ 103%, and RSDs (n = 6) were less than 10%.
