| dc.description.abstract | A simple method was developed by combining dispersive liquid-liquid microexraction (DLLME) and flame atomic absorption spectrometry (FAAS). For the pre-concentration of trace amounts of cadmium, a new complexation chelate of 2-[(4-phenylpiperazine-5-Thioxo- 4,5-dihydro-1 ,3,4-oxadiazole-2- yl)methyl]-5-methyl-4-[2-(1H-indol e-3-yl)ethyl]-2,4-dihydro-3H-1, 2,4-Triazole-3-one (PPTOMDT) was used and mixed with the solvents of chloroform and methanol. The mixture of the extraction solutions was then directly injected into an aqueous solution containing Cd2+ ions. After centrifugation, the settled phase was diluted with 500 mu L of ethanol/nitric acid and aspirated into the FAAS. The limit of detection (LOD) was found at 0.69 mu g L-1 under optimum conditions. The relative standard deviation (RSD) for 15 replicates at a 3.75 mu g L-1 Cd2+ concentration level was 3.21%. The calibration plot was linear within the range of 2.5-15 mu g L-1 of Cd2+. After the analytical characteristics were determined, the CRM-TMDW-500 Drinking Water and CRM-SA-C Sandy Soil C, both certified reference materials, were analyzed in order to validate the method. The application of the DLLME method has been successfully tested for the determination of cadmium in solid and liquid samples. The recoveries of the spiked sample ranged between 92-96%. | |
