An ion-selective electrode system for continuously monitoring cyanide ion, based on a computerized gran plot
Abstract:
A procedure for the continuous monitoring of cyanide ion with an ion-selective electrode is described, based on the use of the Gran plot standard-addition technique. The mean concentration of the sample reservoir is measured continuously during a time span of 6 min. The use of a computer programme facilitates calculation of the results. Because the combined weights of several data points are used to calculate the unknown concentration, random errors tend to be eliminated and in addition there is no need for reference calibration curves.
