The photosensitized oxidation of 2-chlorophenol (2-CP) in aqueous solution using immobilized meso-tetraphenylporphyrin (TPP) in polyurethane nanofabrics was studied. The influence of various parameters on the reaction efficiency was investigated, i.e., 2-CP concentration, oxygen content and pH of the reaction solution and the stability of immobilized photosensitizer at the multiple use. The resistance of the structure of the photosensitizer carrier toward the solutions of various pH was also studied. The participation of molecular singlet oxygen (O-1(2)) in the photooxidation was tested using NaN3 and imidazole quenchers of O-1(2). The kinetics of the process was described using Langmuir-Hinshelwood model.
