The organic matter (OM) entering the water–steam cycle of a power plant has been considered as one potentially serious contaminant in the industry. Therefore, the thermal decomposition characteristics of humic acid (HA) were investigated at an elevated temperature in a stainless steel autoclave through ion chromatography and total organic carbon analysis methods. The concentrations of the impurity anions varied with the changes in HA concentration and pyrolysis time. In addition, the different contents of thermal decomposition products in the ...
