Abstract：The content of arsenic,antimony and bismuth in laterite nickel ore was determined with hydride generation-atomic fluorescence spectrometry(HG-AFS).The influencing factors were discussed in detail.The aqua regia bath was adopted for reducing the volatile loss of elements to be tested,while the mixed solution of thiourea and ascorbic acid was used as masking reagent to eliminate the impact of interfering elements.The detection limit of method was between 0.10-0.25 ng/mL.The arsenic,antimony and bisnmuth in laterite nickel ore was analyzed with the recovery of 91%-113% and relative standard deviation(RSD）of 1.9％-7.6%
