Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA ELABORACION DE SOLUCIONES DE PEROXIDO DE METAL ALCALINO ACUOSAS, EN DONDE LA RELACION MOLAR DEL METAL ALCALINO CON RESPECTO A H{SUB,2}O{SUB,2} SE ENCUENTRA ENTRE 0,5 Y 2,5 EN UNA CELDA ELECTROQUIMICA, CONSISTIENDO EN UN CATODO DE DIFUSION DE OXIGENO POROSO, UNA MEMBRANA DE INTERCAMBIO DE CATIONES Y UN ANODO, UN ELECTROLITO CONTENIENDO ACIDO SULFURICO QUE FLUYE A TRAVES DE LA CAMARA DE ANODO, UN ELECTROLITO CONTENIENDO UN HIDROXIDO DE METAL ALCALINO QUE FLUYE A TRAVES DE LA CAMARA DE CATODO, Y UN PEROXIDO DE METAL ALCALINO QUE SE FORMA MEDIANTE REDUCCION CATODICA DE OXIGENO. EN EL PROCEDIMIENTO EL SULFATO DE HIDROGENO DE METAL ALCALINO ESTA INCLUIDO EN UN CIRCUITO ELECTROLITICO, SIENDO EL MATERIAL DE COMIENZO PARA EL SULFATO DE HIDROGENO DE METAL ALCALINO UNA SOLUCION ACUOSA DE SULFATO DE METAL ALCALINO O SULFATO HIDROGENO O UNA MEZCLA DE SULFATO DE METAL ALCALINO Y SULFATO HIDROGENO O UNA SOLUCION ACUOSA DE SULFITO DE METAL ALCALINO O SULFITO HIDROGENO,O UNA MEZCLA DE SULFITO DE METAL ALCALINO Y SULFITO HIDROGENO O UNA SOLUCION ACUOSA DE CARBONATO DE METAL ALCALINO O CARBONATO HIDROGENO O UNA MEZCLA DE CARBONATO DE METAL ALCALINO Y CARBONATO HIDROGENO, UNA SOLUCION ACUOSA DE ACIDO SULFURICO O PURA, UN DIOXIDO DE SULFURO GASEOSO O PURO, SIENDO PRODUCIDO DIOXIDO DE CARBONO GASEOSO.
