Sažetak
Dibutyl phthalate (DBP) is an additive widely used in cosmetics and plastics. Since DBP does not form chemical bonds with the polymer matrix, there is a high potential for it to leach out of the products during their usage or disposal. DBP is listed as Substance of Very High Concern due to its endocrine disrupting behavior and reproductive toxicity, which increases the awareness for its removal from the environment.[1] In this study, the photochemical degradation of DBP in UV-C/H2O2 and UV-C/Na2S2O8 processes was conducted. The influence of pH-value and oxidant concentration was observed, and the optimal conditions were determined. The results showed pseudo-fist order degradation constants for both processes, while UV-C/Na2S2O8 process showed several times higher degradation rate of DBP.
