Abstract
In the present study, a simple method as name dispersive liquid-liquid microextraction was developed for the thorium extraction. In this extraction method, acetone as a disperser solvent and chlorobenzene as an extraction solvent was used. Extraction and separation of thorium with complexing agent cyanex 272 in an acidic environment were performed. Some of the effective parameters on the extraction of thorium such as type and volume of extraction and disperser solvents and concentration of ligand and type and concentration of acid were studied and optimized. Under the optimum conditions, good linearity was observed in the range of 1.0-5000 µg/L with the correlation coefficient (r2) > 0.997. The limit of detection (LOD) was 0.3 µg/L. Repeatability for five replicate measurements in the concentration level of 20.0 µg/L was 6.5% and extraction recovery 78% was obtained.
