The TiO2 solar-photocatalytical degradation of the pesticide carbofuran (CBF) in water, at laboratory- and pilot-scale, was studied. At laboratory-scale the evaluation of CBF concentration (14-282 μmol/L) showed that the system followed a Langmuir-Hinshelwood kinetics type. TiO2 concentration (0.05-2 g/L) and initial pH (3-9) were also evaluated and optimized using the surface response methodol. and the Pareto diagram. In the range of variables studied, initial pH 7.60 and 1.43 g/L of TiO2 favored the efficiency of the process. Under optimal conditions the evolution of substrate, COD, dissolved organic C, toxicity and organics byproducts were evaluated. In the pilot-scale tests, using direct sunlight, 55 mg/L of CBF in a com. formulation was eliminated after 420 min; while after 900 min of treatment 80% of toxicity (1/E50 on Vibrio fischeri), 80% of COD and 60% of dissolved organic C were removed. The anal. and evolution of 5 CBF byproducts, as well the evaluation of the treatment in the presence of isopropanol or using acetonitrile as a solvent suggest that the degradation is mainly carried out by [rad]OH radical attack. A schema depicting the main degradation pathway is proposed. In the experiment, the researchers used many compounds, for example, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8HPLC of Formula: 1563-38-8).
2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.HPLC of Formula: 1563-38-8
