چکیده
In this research, meta-(۴-bromobenzyloxy) benzaldehyde thiosemicarbazone (MBBOTSC) as a novel ligand was synthesized from the reaction between meta-(۴-bromobenzyloxy) benzaldehyde and thiosemicarbazide under basic condition in water and ethanol as solvents. Ligand has the ability to chelate ions and therefore, it was used to form a complex and extract ions. So, the cadmium ions in water and wastewater samples were separated based on MBBOTSC by ultrasound assisted-dispersive-ionic liquid-liquid microextractionmethod (USA-D-ILLME) before determination by AT-F-AAS.The MBBOTSC ligand was added to the mixture of the ionic liquid/acetone(IL/AC, [OMIM][PF۶]) and then injected by syringe to ۵۰ mL of water samples at pH ۶-۷.The sample was put into the ultrasonic accessory for ۵ minutes, after complexation (Ligand-Cd; RS…Cd….RS), the water sample was centrifuged for ۳ min for phase separation.Due to complexation and back-extraction of Cd in liquid phase,the amount of Cd ions in the water samples was determined by AT-F-AAS after dilution eluent (۰.۵ M, HNO۳) with DW up to ۱ mL.In optimized conditions, the Linear ranges and LOD for ۵۰ mL of water samples were obtained ۱-۳۶μg L-۱and ۰.۳μg L-۱, respectively (Mean RSD= ۱.۲۶%). The validation results were successfully achieved by spiking real samples and using electrothermalatomic absorption spectrometry (ET-AAS).کلیدواژه ها
