Separation and preconcentration of cadmium ions using octadecyl silica membrane disks modified by methyltrioctylammonium chloride
A simple and selective method for the determination of cadmium in water samples by FAAS after solid phase extraction has been developed. The method is based on the sorption of cadmium as CdI 4 2− on octadecyl silica membrane disks modified by cationic surfactant of methyltrioctylammonium chloride in...

−1 nitric acid in ethanol and is measured by flame atomic absorption spectrometry. The influence of flow rates of eluent and sample solution, iodide concentration and amount of surfactant in retention and elution of cadmium from disks was also investigated. A preconcentration factor of 100 was achieved by passing 1000
ml of sample through the membrane disk. The limit of detection (LOD) of cadmium was found to be 0.014
