Abstract
A spectral and luminescence study was made of the efficiency of phototransformation of sulfaguanidine in water under irradiation with an OUVb-04 ultraviolet lamp (180–275 nm) and KrCl (222 nm), XeBr (282 nm), and XeCl (308 nm) excilamps. An analysis of the conversion of sulfaguanidine in water showed that the efficiency of sulfaguanidine phototransformation in water under irradiation with the XeBr excilamp is comparable to the loss under irradiation with OUVb-04, but higher than those under irradiation with the KrCl and XeCl excilamps. The maximum loss of sulfaguanidine is 99% without the introduction of additional oxidizing agents. After irradiation, several photoproducts of various nature were detected.
