El uso del potencial redox en muestras ambientales

Abstract

El objetivo del presente trabajo fue estudiar la posible contaminación ocasionada por los efluentes vertidos por el Hotel Internacional Potrero de los Funes sobre las aguas provenientes del rebalse del dique Potrero de los Funes, que forman el arroyo Cuchi Corral, usando un parámetros de fácil y rápida medida como es el potencial redox. Los muestreos se realizaron en forma bimestral durante el año 2005 -2006 y en cuatro sitios de muestreo, RD (rebalse del dique a partir del cual se forma el arroyo), EH (efluente del hotel), AC1 y AC2 (ubicados a 20 metros y 900 metros respectivamente de la mezcla del rebalse y efluente de hotel) Se realizaron determinaciones de parámetros físico-químicos (DBO, DQO, OD, pH y potencial redox) utilizando los métodos descriptos en el Standard Methods for Examination of Water and Wastewater. Dada la precisa relación que existe entre materia orgánica (DBO y DQO) y las características redox de un sistema, puede continuarse en el futuro el monitoreo, de este tipo de contaminación en este cuerpo de agua, en forma rápida y simple con la medida del potencial redox.

The purpose of this study was to evaluate the stream´s pollution by wastewater from a hotel. The samplings were realized once every two months during the year 2005 to 2006. The studied sites are: RD (dam from which the stream is formed), EH (effluent of the hotel), AC1 and AC2 (located at 20 meters and 900 meters from the mixture of dam and effluent of hotel, respectively. Determinations of BOD, COD, DO, pH and redox potential were carried out using the methods describe in the Standard Methods for Examination of Water and Wastewater. The result showed that exists a relationship between organic matter (BOD and COD) and the characteristic redox of system. In the future, the stream can be monitored with the measure of the potential redox.
