| Abstract: | A method for the determination of arsenic in gold by hydride generation-none dispersion atomic fluores-cence spectrometry was proposed. The conditions for sample digestion and hydride generation were chosen and opti-mized by the experiments. The detection limit of the method for arsenic is 0.000 01% and the recovery rate is 92%-103% with precision of 0.2%-1.8% RSD（n=7）. |
