Abstract

PROCEDIMIENTO PARA LA ELIMINACION QUIMICA DE SOLDANTES DE ESTAÑO Y DE ALEACION DE ESTAÑO-PLOMO DE UN SUSTRATO.CONSISTE EN HACER REACCIONAR UNA SOLUCION ACUOSA DE PEROXIDO DE HIDROGENO, BIFLUORURO AMONICO O FLUORURO AMONICO, UN ACIDO Y UN COMPUESTO COMPLEJANTE DE 8-HIDROXIQUINOLINA, CON EL DEPOSITO DE SOLDANTE, DURANTE EL TIEMPO NECESARIO PARA ELIMINAR PRACTICAMENTE LA TOTALIDAD DE DICHO SOLDANTE SIN ATACAR SIGNIFICATIVAMENTE EL CITADO SUSTRATO. LA CONCENTRACION DE PEROXIDO DE HIDROGENO ESTA COMPRENDIDA ENTRE 0,1 Y 10M, LA DE BIFLUORURO AMONICO O FLUORURO AMONICOESTA COMPRENDIDA ENTRE 0,4 Y 10M, Y LA DEL COMPUESTO 8-HIDROXIQUINOLINA ES DE 0,005M COMO MINIMO. LA CANTIDAD DE ACIDO UTILIZADA HA DE SER LA NECESARIA PARA QUE SU CONCENTRACION PUEDA MANTENER EL PH ADECUADO DE LA SOLUCION.
