An accurate and highly sensitive spectrographic method for the determina tion of ultratrace gold was reported. This method was based on the use of a small activated carbon column for collecting gold. The quantity of the activa- ted carbon used in the column was so arranged that the weight of the ash formed after ignition was about 0.1-0.15mg. The ash was then subjected to spectro- graphic determination. This method can be applied in the concentration range of 0.1-3000 ppb of gold. The coefficient of variation of gold was 20-27% for geological materials containing O.x-xppb of gold. Calibration curve was linear in the range of 2 ng-30ng of gold. The detection limit was 1-2ng.
