This specific silver ion selective electrode (ISE) operates based on the principle of ion-selective permeability, where the electrode's membrane selectively allows silver ions to pass through while excluding interference from other ions.
Tips: Are there any sample preparation requirements for using silver ISE?
For the successful use of a silver ion-selective electrode (ISE), proper sample preparation is crucial. Ensure that the sample is free from contaminants that might interfere with silver ion measurement. Begin by filtering the sample to remove particulate matter and use deionized or distilled water in the preparation process. Adjust the pH of the sample to the recommended range for silver ion measurement, typically around pH 2-3. This adjustment helps maintain electrode stability and enhances measurement accuracy. Avoid using samples containing complexing agents or substances that can form precipitates with silver ions. Additionally, standardize the electrode with known silver ion concentrations before measuring unknown samples. Adhering to these sample preparation guidelines will optimize the performance and reliability of the silver ISE in determining silver ion concentrations in various solutions.
