Photo-Fenton method usage to organic compounds degradation

The aim of conducted research within this work was the decomposition of chosen pesticides with the use of Fenton's method supported by UV radiation and strong halogen light. The experiments were done with the use of such pesticides as chloropiryphos, metribuzyne, and metriam included in popular plant protection products. In order to support the highest possible effect of pesticides degradation, the decrease in hydrogen peroxide dose and catalyst, there was conducted the research connecting irradiation by strong halogen lamp with the power of 400W and UV lamp with the wave length of 350 nm. In the process of pesticides removal, irradiation process was conducted during mixing of samples with Fenton's reagent. In conducted experiment, the past sell-by date chemicals were degraded in stages into simpler compounds. The conditions cause the acceleration of reaction in comparison with the one occurring without any light support. However, the processes described above are occurring slowly, which eliminates their use in practical technology of solution treatment. This thesis is proved by the research conducted by article's authors.
