| Abstract: | The instrumental neutron activation analysis (INAA) technique has been used to determine 17 major, minor, and trace elements in samples of the three major sources of Nigerian coal. The NBS Standard Reference Material, Coal SRM 1632, was also analyzed, for the purpose of verifying the accuracy of the method. The results obtained with it were in good agreement with the NBS certified values. The concentrations of the major elements determined for the Nigerian coal were found to be much lower than the mean values of those reported for coal samples from other parts of the world. |
