Abstract
SEGUN LA INVENCION SE REGULA EL CONTENIDO EN PERACIDO, EN PRESENCIA DE PEROXIDO DE HIDROGENO, EN UNA SOLUCION (2) DE RELACION MOLAR DE CONCENTRACION DE PEROXIDO DE HIDROGENO/CONCENTRACION DE PERACIDO NO SUPERIOR A 100, POR UN PROCESO SEGUN EL CUAL SE LE ASPIRA POR UNA BOMBA (3) EN LOS CIRCUITOS DE ASPIRACION DE DOS BOMBAS (5, 6) QUE FUNCIONAN EN EL MISMO VOLUMEN Y PUEDEN ASPIRAR SIMULTANEAMENTE UN LIQUIDO (9) DE DILUCION Y/O DE AJUSTE DEL PH, LA BOMBA (5) ALIMENTA LA CURA DE REFERENCIA (7) DE UN FOTOMETRO BI-HAZ Y LA BOMBA (6) ALIMENTA SU CUBA DE MEDIDA (8), Y LOS VOLUMENES DE LAS BOMBAS (3, 5, 6) ESTAN AJUSTADOS DE MANERA QUE LA CONCENTRACION DE PERACIDO EN EL FLUJO DE MEDIDA (10) SEA INFERIOR A APROXIMADAMENTE 100 PPM EN PESO, SE AÑADE AL FLUJO DE MEDIDA (10) QUE SALE DE LA BOMBA (6) UN EXCESO DE YODURO (11) MEDIANTE UNA BOMBA (13), UNA UNIDAD DE MEDIDA (14) A LA QUE ESTAN CONECTADAS LAS CELULAS DEL FOTOMETRO COMPARA LA INTENSIDAD DEL COLOR DE YODO FORMADO EN LA CUBA DE MEDIDA (8) CON LAREFERENCIA EN LA CUBA DE REFERENCIA (7) Y TRANSFIERE LA DIFERENCIA A UN REGULADOR (16) QUE ACCIONA, SI ES NECESARIO, UNA BOMBA DE INYECCION (19) DE UNA SOLUCION DE PERACIDO (20) EN LA SOLUCION (2). APLICACION EN PARTICULAR A LA DETERMINACION Y A LA REGULACION DEL CONTENIDO DE ACIDO PERACETICO EN LAS SOLUCIONES INDUSTRIALES DE DESINFECCION.
