离子选择电极互参电位法研究

studies of the Mutual Refrence Method in Ion Selective Electrode

互参电位法是一种无液接电位、受离子强度及试液体积变化影响少的电位分析新方法。该方法操作简便,可同时测定试液中两种离子。本文从原理和实践上对互参电位法进行了论证,并研究了它的适用条件和范围。

The mutual reference method in the ion selective electrode can be applied to successive determination of two different ions in a solution. No liquid junction potential is found in this system. The pffect of ionic strength and volume of the test solution on the method is insignificant. The various analytical techniques have been demostrated in theory and in practice, the optimum experimental conditions and the applicable range are also given.
