- This second quarterly report deals with evaluation of the fly ash sorbate characteristics for removal of organics in ash pond effluent as measured by Chemical Oxygen Demand (COD) and Arsenic. The Moessbauer spectra is being interpreted to identify the form of the iron compounds present in the fly ashes resulting from the different combustion conditions encountered in the three different types of coal fired boilers used in this investigation and also in the coal burned in these boilers. The results indicate that boiler conditions which produce fly ashes with sorbate characteristics that favor the removal of cations also favor the removal of the anion arsenic. The effectiveness of the fly ashes for removal of COD could not be determined because the ash pond effluents used were found to contain chloride concentration levels that interfered with the COD determination. Interpretation of the Moessbauer spectra revealed that the chemical state of the iron in both the coal and the resulting fly ash can be used to monitor the fluid nature of the ash in the boiler. The results also indicated that the chemical state of the iron in the eastern coals used in this study can influence the fusion temperature of the ash.
