Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA DETERMINAR ININTERRUMPIDAMENTE LA PRESENCIA DE DIMETILFORMAMIDA Y DE DIMETILAMINA EN SOLUCIONES ACUOSAS, ESPECIALMENTE EN LAS AGUAS INDUSTRIALES, QUE SE CARACTERIZA POR QUE SE QUITA, A LA CORRIENTE DE AGUA, CONTINUAMENTE, UNA PARTE DEL CAUDAL. A ESTA CORRIENTE PARCIAL -EN CONDICIONES CONSTANTES SOLUCION ALCALINA DOSIFICADA CON VELOCIDAD CONSTANTE, Y SE LA SOMETE A UNA VAPORIZACION PARCIAL EN CONDICIONES DE VAPORIZACION CONSTANTES; SE CONDENSA LA CORRIENTE DE VAPOR OBTENIDA POR MEDIO DEL FRIO; EN EL CONDENSADO SE DEFINE, DENTRO DE UNA CELULA DE MEDIDA DE LIQUIDOS CONTINUAMENTE, LA CONDUCTIVIDAD ELECTRICA Y SE CONVIERTE EL VALOR DE MEDIDA OBTENIDO, CON UNA CURVA DE CONTRASTE O CON FORMULAS CONOCIDAS, EN EL VALOR DESEADO DE CONCENTRACION.
