Experimental results of degradation of ethylenediaminetetraacetic acid (EDTA) under pulsed broadband UV radiation in the presence of hydrogen peroxide are presented in this article. The object of research was an aqueous solution containing EDTA with the initial concentration of 15 to 100 mg/l and sodium nitrate (NaNO₃) with the initial concentration of 4 g/l. Energy consumption for degradation and complete mineralization of ethylenediaminetetraacetic acid degradation products was estimated depending on the initial concentration of the acid, presence or absence of sodium nitrate and hydrogen peroxide at the concentration of 3 g/l.
