Моделирование кондуктометрического метода измерений показателя pH в смеси растворов кислот и щелочей

Abstract

The model of non-straight method of pH factor measurement in acid-alkali mixture based on measurement of material quantity in separate components of mixture is described. Mathematical model allows us to calculate tolerable meanings of metrological characteristics of measurement channels and technical cha?-acteristics of the object of measurement (i. e. volumes and concentrations of mixing solutions). Analysis held in this work allows us to consider that conductivity measurement method for the determination of the pH factor in acid-alkali mixture can be used for the automatization of the process of neutralization of acid and alkali washing processing wastes of industrial plants for which traditional pH-measuring methods are not available because of large amount of disperse deteriorations in objects of measurement.
