Résumé
The photocatalytic degradation of Methyl orange has been investigated on dynamic solar pilot plant using non-woven fibers coated with TiO2 as photocatalyst. The operational parameters, such as initial dye concentration and pH, were studied. Disappearance of color and substrate together with decreases in chemical oxygen demand (COD) and total organic carbon (TOC) content were observed. The photo-decomposition followed pseudo-first-order kinetics. In addition, the toxicity of some by-products was tested using the earthworm (Eisenia andrei) avoidance test. High sensitivity of E. andrei towards soil wetted with MO solution was observed, while no effects were seen for the same solution after photocatalytic oxidation.
