Abstract: The TiO2-mediated photomineralization of 5.0x10-6 - 5.0x10-7 M aqueous solutions of dichloromethane (DCM), tetrachloroethene (PCE), and mono-, di-, and trichloroethanoic acids (MCEA, DCEA, and TCEA respectively) was studied at 296+- 2 K, using PHOTOPERM CPP/313 membranes containing immobilized 30+- 3 wt% TiO2, and, in some of the runs with PCE, 7 wt% of photocatalytic promoters based on CoIII, Vv, and FeIII organometallic compounds. Disappearance of both substrate and total organic carbon (TOC) was examined, as well as chloride ion formation. The apparent reaction order being unit in the range of concentration considered, half times for these three kinetic processes have been measured in a PHOTOPERM WW membrane module, fitted with 1 m2 of membrane, with an absorbed radiating power of 31 W, and saturated with air.
