  • MERCURY UV LAMP WITH IMPROVED ACTINIC SPECTRUM
    Publication number: 20120319011
    Abstract: A low-pressure mercury or amalgam lamp with praseodymium (Pr) doped particles of lanthanum phosphate converts 185 nm radiation to UV-C (186 nm-280 nm). For water purification, a plurality of low-pressure mercury or amalgam lamps with phosphor that convert 185 nm radiation to UV-C (186 nm-280 nm) may be used. A method for photolysis of nitroso dimethyl amine (NDMA) may include passing electrical current through a low pressure mercury or amalgam lamp, radiating 254 nm radiation through the lamp envelope into water containing the NDMA, converting 185 nm radiation within the lamp into 230 nm-240 nm radiation within the lamp via a phosphor within the lamp, and radiating the 230-240 nm radiation through the lamp envelope and into the water containing the NDMA, with the radiation from the lamp photolysizing the NDMA.
