چکیده مقاله:
Cloud point extraction and spectrophotometric determination of trace quantities of cadmium in some vegetables have been developed.The research area for vegetables analysis was near to the Zarin Shahr where the soil received heavy metals from the EsfahanSteel Company. Cloud point extraction used dithizone as complexing agent and non ionic surfactant Triton-X114 as micellar phase.Several important variables affecting the separation and determination process were optimized. Under optimized conditions calibrationgraph was linear in the range of 1.0-180 ng mL-1 with detection limit of 0.2 ng mL-1. Preconcentration of 10 mL of samples gavean enhancement factor of 50. The proposed method was applied for determination of Cd(II) in vegetable samples with satisfactoryresults.
