Abstract
The analytical advantages of some novel approaches to atomisation using gaseous sample transport and slurry nebulization have been investigated and applied to the determination of trace metals in coal. A cold vapour atomic fluorescence spectroscopic method for the determination of mercury using a gas-sheathed atom cell and front surface illumination was developed. With a manual injection technique the detection limit was 0.01 ng. Replacement with a continuous flow system yielded a more rapid and precise method with a detection limit of C.045 ng.ml-¹. Quantitative recoveries of mercury from a standard coal were obtained through liberation of the analyte using nonoxidative pyrolysis .
