Abstract

SE PROPORCIONA UN PROCEDIMIENTO PARA DETERMINAR LAS RELACIONES DE CONCENTRACION CAB DE DOS ELEMENTOS, A,B, DE UNA SUSTANCIA, A PARTIR DE LAS RELACIONES DE INTENSIDAD IAB DE DOS LINEAS ESPECTRALES DE ESTOS ELEMENTOS, EN UN PLASMA DE ESTA SUSTANCIA. EN ESTE PROCEDIMIENTO, SE MIDE, ADEMAS DE LA RELACION DE INTENSIDAD IAB LA RELACION DE INTENSIDAD IC1,2 DE DOS LINEAS ESPECTRALES 1 Y 2,DE UN ELEMENTO C,CON LAS ENERGIAS DIFERENCIALES DE ELEVACION E1 Y E2 Y SE DETERMINA A TENOR DE LA ECUACION (1) DE LA RELACION DE CONCENTRACION CAB. LA CONSTANTE K SE CALCULA PREVIAMENTE, A PARTIR DE UNA RELACION DE CONCENTRACION CONOCIDA C''AB DEL ELEMENTO A Y B DE UNA SUSTANCIA HOMOLOGABLE Y DE LAS RELACIONES DE INTENSIDAD PERTINENTES, MEDIDAS EN EL ESPECTRO DEL PLASMA I''AB E IC1,2, A TENOR DE LA ECUACION 2 (2). ADEMAS HAY QUE TNER EN CUENTA UNA ZONA DE EVALUACION LIMITADA PARA IAB, I''C1,2 Y C''AB.
