Abstract

The quantitative analyses of trace elements in some Nigerian coals have been investigated in this research. Four samples of coal collected from the following locations: Enugu (onyeama), Ogwashi-Azagba, Orukpa and amansiodo were studied. The samples were washed, dried, pulverized, digested and subsequently subjected to flame absorption spectrometry for the trace elements determination. Among the trace elements observed were trisulphide (So3 - ), iron (Fe), calcium (Ca), potassium (K), magnesium (Mg), silicon (Si) and sodium (Na). Iron (Fe) was observed to have the highest percentage weight in all the samples with the highest composition (0.635%) in Amansiodo coal and least composition (0.236%) in Ogwashi-Azagba coal. Silicon on the other hand was observed to have the least composition (< 0.002%) in all the samples while the percentage composition of the rest (trace elements) lies in between the range 0.636% - < 0.002%). However, the composition of trace elements in the various samples varies as shown in figures 4.0 – 4.5 respectively
