• We have used a modified selective leaching procedure to reveal the mode of occurrence of trace elements in coal. The data are reported here with SARM coal. The leaching results of Cr and Cd were most striking. Cr was only slightly removed from raw coal with both HCl and HNO_3 but it was significantly leached out from the low-temperature ash. This strongly suggests the association of Cr with the organic matrix. The leaching behaviors of Cd in different acids as well as from ashes are extremely similar to Fe, suggesting that Cd is likely to be associated with pyrite. Experiment was also conducted to leach a fly ash sample.
