Arada Pérez, María de los Angeles; Yazdani-Pedram Zobeiri, Mehrdad; Cortés Nodarse, I.; Lazo, A. R.; Serrano M., M. (Ministerio de Educación Superior, 2003)Nitrate concentration in drinking water was directly determined by employing an ion selective liquid membrane electrode (ISE). This was constructed with poly(vynil chloride) as matrix on a solid conducting support. ...
