Comparative Efficiencies for Phenol Degradation on Solar Heterogeneous Photocatalytic Reactors: Flat Plate and Compound Parabolic Collector

Phenol is a recalcitrant anthropogenic compound whose presence has been reported in both wastewater and drinking water; human exposure to phenolic substances can lead health problems. The degradation of phenol (measured as COD decrease) through solar heterogeneous photocatalysis with immobilized TiO2 was performed two different reactors: flat-plate reactor (FPR) parabolic collector (CPC). A 23 full factorial experimental design followed. variables were the TiO2, H2O2 addition, type reactor. Data fitted pseudo-first-order reaction-rate-kinetics model. rate constant for photocatalytic 1 mM 6.6 × 10?3 min?1 FPR 5.9 CPC. calculated figures merit analyzed MANCOVA, UV fluence covariate. An ANCOVA showed that reactor, or had no statistically significant effect on results, but there TiO2. According (p < 0.05). CPC average 17.4% more efficient than when it came area per order (ACO) by addition.
