EPA 9212

Potentiometric Determination of Chloride in Aqueous Samples with Ion-Selective Electrode

Applicability: EPA Method 9212 is applicable to measuring total solubilized chloride in various water sources and soil extracts. Specifically, it can be used for drinking water, surface water, groundwater, wastewater, and soil extracts. The method utilizes a chloride ion-selective electrode and a potentiometric technique to determine chloride concentrations.

Purpose: The core purpose is to determine the amount of chloride present in water and soil samples using a potentiometric method, specifically with an ion-selective electrode.
