Abstract
A non‐suppressed ion chromatographic (IC) method has been developed for the monitoring of strontium in the presence of a large excess of alkali and alkaline earths. The mobile phase consisting of ethylenediamine (EDA) and organic acid as a complexing agent has been optimized in combination with a high‐speed cationic column. The reported method has been tested, successfully, to monitor strontium in coastal Arabian seawater with a coefficient of variation 2 (n = 5). The reported results have been compared with ICP‐OES analysis and are in agreement.
