Abstract
Veratrole and guaiacol were chosen as the model compound of the aromatic moieties of lignin and the mechanisms in degradations of them were proposed. In order to elucidate the mechanism of wastewater by ozonolysis, the wastewater was compared with the model compound using several indexes which were measured by the experiments. The experimental data which were used as the indexes were absorbance of 280 nm and absorbance of 280 nm after reduction by hydrogen, amounts of methoxyl, phenolic hydroxyl and oxalic acid. In the ozonolysis of wastewater, absorbance of 280 nm and amount of oxalic acid were lower than that of model compound to some extent, but other indexes were in agreement each other. Experimental results confirmed that the mechanism of model compound was in agreement with that of wastewater.
