Trace elements distribution during mild pyrolysis of low-rank coal
1998
The distribution trace elements of the coals during mild pyrolysis process was studied. Atomic absorption spectrometry with Zeeman correction (AAS) and inductively coupled plasma spectrometry (ICP) were used for determination of several trace and major elements in coal and products of coal mild pyrolysis process. The organic matter of coals and solid products of this process have been removed from mineral matter (MM) by cool oxygen plasma oxidation (COPO).
