Abstract

For study of photodegradation, an excilamp on working molecules KrCl with ^λ_rad = 222 nm, developed at the Institute of High Current Electronics of the SB RAS, was used as source of UV radiation. The results of direct photolysis of phenoxyacetic acids herbicides in aqueous solutions are discussed. The phototransformation occurs more slowly when the herbicides concentration increases. The use of the flow-through reactor is more effective than operation in the stationary conditions. The prospect of using a wide range of excilamps with different characteristics for solving environmental problems is highlighted.
