| Abstract | : | Heavy metals in the samples of coals and combustion residues (bottom ash and fly ash) from Pacitan coal-firedpower plant (CPP) have been identified by using NAA, XRF, and ICP-OES methods. This research was aimed tounderstand the analysis results correlation coefficient (R) and determine the enrichment ratio (ER) value of thesamples by using three analysis methods. The results showed 10 elements have been simultaneously detected in allsamples. The correlation coefficient of analysis results of metals content in coals by using NAA-XRF, XRF-ICP OESand with ICPOES-NAA methods gives R2?1 respectively. The correlation coefficient of analysis results of metalscontent in bottom ash and fly ash by using the methods of NAA-XRF, XRF-ICPOES, and ICPOES-NAA gained R2?1respectively. ICP-OES method was most satisfactory in this study. The value of ER for identified metals by using thethree methods in the samples of bottom ash and fly ash yielded the value over one, and ER value of fly ash wasgreater in comparison to the bottom ash |
