Determination of Iodides from Groundwater and Surface Water using an Optimized Ion Chromatographic Method

Abstract

The research aimed to provide an optimized method for the determination of iodides concentration in groundwater and surface water sources using ion chromatography technique. The analyses were conducted by using a conductivity detector, with a 35 mM KOH mobile phase, at a flow rate of 1 mL/min, the temperature in the detector chamber and the intensity of the suppressor current being set at 350C and 87 mA, respectively. The interferences given by other ions were also investigated, and the performance parameters were determined such as detection limit, quantification limit, accuracy, and recovery.
