Metal phthalocyanines in the presence of visible light are applied in the semi-pilot level for the 15 degradation of organic pollution represented by 4-chlorophenol (4-CP) with potential further scale16 up. The effectiveness of the process based on the generation of singlet oxygen active species is 17 compared with commonly used method of photochemical oxidation with hydrogen peroxide in the 18 presence of ultraviolet irradiation. The direct comparison of the reaction systems was conceivable 19 because both oxidation processes were carried out in identical experimental arrangements and under 20 identical reaction conditions. The comparison was performed in terms of 4-CP conversion, TOC 21 removal, apparent quantum yields, kinetic constants, and economy considerations. It must be 22 emphasized there have been no reports on the semi pilot scale utilization of phthalocyanines for 23 decontamination purposes previously.
