Abstract

METODO DE SOLIDIFICACION DE SUSPENSIONES RESIDUALES QUE CONTIENEN MAS DE 30% DE ACIDO BORICO. CONSISTE EN TRATAR LA SUSPENSION RESIDUAL CON METASILICATO SODICO EN LA PROPORCION DE 0,1 A 0,4 PARTES DE METASILICATO SODICO POR CADA PARTE DE SUSPENSION, Y MEZCLAR INTIMAMENTE HASTA QUE SE PRODUCE UN AUMENTO SUBITO DE LA VISCOSIDAD. CUANDO LA SUSPENSION RESIDUAL SE HA NEUTRALIZADO CON HIDROXIDO SODICO, ANTES DE LA ADICION DEL METASILICATO SODICO SE DEBE REDUFIR EL PH, PARA LO CUAL SE TRATA CON UN ACIDO, TAL COMO ACIDO SULFURIUCO. TIENE APLICACIONES PARA REDUCIR LAS CANTIDADES DE RESIDUOS RADIACTIVOS EN LAS INSTALACIONES NUCLEARES.
