Summary:In this study, organic gas steam liquid extraction (OGS-LE) by using a particular homemade extraction cell was proposed to extract and determine cadmium in aqueous solutions. The variables of interest in the OGS-LE method in this research are extraction solvent volume, pH of the aqueous solution, the molar ratio of extractant agent, and heated chamber temperature, which were investigated. Under the optimized conditions, the limit of detection (LOD) and limit of quantification (LOQ) of this method were found to be 0.03 μg L−1 and 0.09 μg L−1 for Cd2+ ions. The linear concentration range was 0.1-1 μg L−1 , and the percent relative standard deviation (RSD %) was 3.7%.
