Abstract

PUEDE PREDECIRSE LA EXTENSION DE LA NEUTRALIZACION DE SUBPRODUCTOS DE ACIDOS ORGANICOS EN SOLUCIONES DE POLIMERO DE ARAMIDO MEDIANTE LA APLICACION DE ESPECTROSCOPIA CERCANA AL INFRARROJO, DENTRO DE LA BANDA DE LONGITUDES DE ONDA DE 800-2200 NM, ESPECIALMENTE 1300-1610 NM. EL METODO REQUIERE EL ESTABLECIMIENTO DE UNA CORRELACION ENTRE EL PORCENTAJE DE NEUTRALIZACION DE LAS MUESTRAS DE UN CONJUNTO DE PRUEBA Y SU ESPECTRO CERCANO AL INFRARROJO, EL DESARROLLO A PARTIR DE LA CORRELACION DE UNA ECUACION PREDICTIVA, LA VERIFICACION DE LA EXACTITUD DE LA ECUACION PREDICTIVA SOBRE MUESTRAS DE UN CONJUNTO DE VALIDACION, Y LA APLICACION DE LA ECUACION PREDICTIVA PARA LA DETERMINACION DE LA COMPOSICION DE MUESTRAS DESCONOCIDAS. LA ABSORBENCIA PUEDE MEDIRSE COMO LA ABSORBENCIA, O COMO LA PRIMERA, LA SEGUNDA, LA TERCERA, LA CUARTA O UNA DERIVADA MAYOR DE ABSORBENCIA O POR OTRAS TECNICAS DE PROCESAMIENTO DE SEÑALES. LA SEÑAL PUEDE UTILIZARSE PARA CONTROLAR UN PROCESO MULTICOMPONENTE MEDIANTE LA MANIPULACION DE LOS DISPOSITIVOS DE ACCIONAMIENTO PARA EL CONTROL DEL PROCESO QUE TIENEN UN IMPACTO CONOCIDO SOBRE LOS COMPONENTES A CONTROLAR.
