9. Analysis of Chemical Structure of Coal by FTIR

Abstract

Forty three coals were analyzed by FTIR and the results were compared to those for other methods. For carboxyl group, the contents in coal obtained from FTIR were quite comparable to those from the conventional chemical analysis using ion-exchange method. The peak ratio of aromatic CH and aliphatic CH for FTIR showed a good relationship with f_a value obtained from solid state ^<13>C-NMR.
