Abstract The combustion procedure previously described for the determination of mercury in coal by cold vapor atomic absorption spectrophotometry has been modified to permit samples to be analyzed more rapidly and with better precision. A coefficient of 8.3% was obtained for the analysis of 7 samples containing 0.1 ppm mercury. In addition a greater variety of types and particle sizes of coal can be analyzed by the modified procedure.
