Abstract
A method of purifying or sanitizing contaminated water to be potable, by exposing the water in the presence of light, to an electrically neutral metal complex of a perfluoroalkylated fluorinated phthalocyanine photosensitizer, having only external R groups with C—F bonds, preferably F64PcZn; whereby, a sufficient quantity of singlet oxygen is provided by the chemical reaction of the light and the photosensitizer to destroy the pollutants or pathogens present in the contaminated water.
