Abstract

UN PROCESO PARA LA DESCOMPOSICION DE MATERIALES ORGANICOS FOTOLITICAMENTE DEGRADABLES QUE INCLUYE EL EXPONER DICHO MATERIAL A LA LUZ ULTRAVIOLETA A MEDIDA QUE EL MATERIAL PASA A TRAVES DE LA SUPERFICIE DE UN DISCO GIRATORIO. EL MATERIAL ORGANICO TIENE FORMA DE UNA DISPERSION LIQUIDA, PREFERIBLEMENTE UNA DISPERSION ACUOSA Y ESTA CONTIENE TAMBIEN DIOXIDO DE TITANIO ANATASA QUE ACTUA COMO CATALIZADOR EN EL PROCESO DE DESCOMPOSICION. EL DIOXIDO TIENE PREFERIBLEMENTE UN AREA SUPERFICIAL ELEVADA. LOS MATERIALES ORGANICOS TALES COMO LOS HIDROCARBUROS, LOS ALCOHOLES, ESTERES, ACIDOS Y OTROS, SE DESTRUYEN MEDIANTE ESTE PROCESO ACEPTABLE PARA EL MEDIO AMBIENTE.
