Abstract

LOS SURFACTANTES DE OXIDO DE AMINA CONTAMINADOS CON NITRITO SON TRATADOS BAJO CONDICIONES ACIDAS CON MATERIALES TALES COMO EL ACIDO MALEICO Y EL DIETILENOTRIAMINOPENTACETATO (DTPA) PARA REDUCIR LOS NIVELES POR DEBAJO DE 1 PPM. DE ESTA FORMA, LA AMINA DE DIMETILO C{SUB,12-13} SE OXIDA CON PEROXIDO DE HIDROGENO EN LA PRESENCIA DE ACIDO MALEICO Y DE DTPA PARA REDUCIR LOS NIVELES DE NITRITO. EL OXIDO DE AMINA RESULTANTE LIBRE DE NITRITO SE EMPLEA EN DIFERENTES COMPOSICIONES DETERGENTES.
