Реферат:
The oxidation of lignin in synthetic aqueous solutions as well as in the biologically treated pulp-andpaper mill wastewater with hydrogen peroxide was studied in various methods: hydrogen peroxide UVphotolysis, homogeneous, heterogeneous and UV-assisted heterogeneous Fenton reactions, catalysed by FeZSM-5 zeolite. Contrasting the low-molecular organic contaminants, the oxidation of lignin in aqueous solutions was drastically slowed down in presence of heterogeneous FeZSM-5 zeolite, showing the superior performance of acidic homogeneous Fenton and hydrogen peroxide photolysis. This is explained by steric hindrance in oxidation of lignin with OH radicals on the catalyst surface and possible deactivation of lignin molecules adsorbed on the zeolite. The hydrogen peroxide photolysis among the
studied delignification methods appeared to be the most efficient one in a wide range of pH.
