Abstract
A comparative evaluation of the efficiency of using mercury-free radiation sources - KrCl excilamp (222 nm) and solar radiation to intensify the oxidative processes of pollutants with different chemical nature in ultraviolet-coupled ferrous (ferric)–peroxydisulfate systems was carried out. The oxidation ability of Fenton-like process for persistent target compounds of inorganic nature - on the example of thiocyanate ion, and bisphenol A (BPA) as the organic one, significantly improved under both UV and solar radiation. In this case, excilamps can be used as an independent or standby source of radiation (with low solar activity or adverse weather conditions), which in the future can be an important factor in ensuring reliability under the modular principle of constructing technological treatment schemes.
