Abstract

PROCEDIMIENTO ANALITICO PARA LA DETERMINACION DE AGUA CON UN REACTIVO DE KARL-FISCHER QUE NO CONTIENE PIRIDINA. CONSISTE EN LA DISOLUCION DE LA MUESTRA OBJETO DE ANALISIS EN UN DISOLVENTE QUE CONTIENE DIOXIDO DE AZUFRE Y UN SUSTITUTO DE LA PIRIDINA, TAL COMO BENZOATO SODICO O AMONIACO, EN PROPORCION ENTRE 2:1 Y 1:2 RESPECTIVAMENTE; ADICION DE UN AGENTE DE VALORACION QUE CONTIENE YODO Y UN DISOLVENTE; Y DETERMINACION DEL PUNTO FINAL DE LA REACCION DE VALORACION. EL PROCEDIMIENTO TIENE APLICACIONES PARA LA DETERMINACION DE AGUA EN UNA GRAN VARIEDAD DE MUESTRAS.
