Abstract

UN METODO DE TRATAR CON UN FOTOCATALIZADOR EL AIRE EN UNA HABITACION DE PACIENTE CONTAMINADA DE BACTERIA Y EN UNA HABITACION QUE FLOTAN SUSTANCIAS MALOLIENTES. UNA PELICULA DE UN CATALIZADOR OPTICO QUE CONSTA DE UN SEMICONDUCTOR, TAL COMO DIOXIDO DE TITANIO ES PUESTO EN LA SUPERFICIE INTERIOR DE UNA PARED DE UNA HABITACION DE PACIENTE O EN UNA HABITACION DE DOMICILIO. LA PELICULA FOTOCATALIZADORA ES IRRADIADA CON LA LUZ DE UNA FUENTE DE LUZ DE ILUMINACION GENERAL, TAL COMO UNA LAMPARA FLUORESCENTE, Y OPTICAMENTE EXCITADA CON UNA PEQUEÑA CANTIDAD DE RAYOS ULTRAVIOLETAS CONTENIDOS EN LA LUZ DE LA LAMPARA FLUORESCENTE. EL VATAJE DE LA LAMPARA FLUORESCENTE Y LA DISTANCIA ENTRE LA PELICULA FOTOCATALIZADORA Y LA LAMPARA FLUORESCENTE SON SELECTIVAMENTE DETERMINADOS TAL QUE LA INTENSIDAD DE LOS RAYOS ULTRAVIOLETAS, LA ENERGIA DE LOS CUALES NO ES MENOR QUE LA ENERGIA DE SALIDA DE BANDA DEL FOTOCATALIZADOR LLEGA A 0.001-1 MW/CM2, PREFERIBLEMENTE 0.01-0.1 MW/CM2. LA BACTERIA Y LOS COMPONENTES QUIMICOSDEPOSITADOS EN LA PELICULA EXCITADA OPTICAMENTE SON FOTODESCOMPUESTOS.
