Abstract
8-Hydroxyquinoline immobilized on polyacrylonitrile hollow fiber membrane was synthesized and used for the preconcentration of cadmium, lead, copper, mangenese, bismuth, indium, cobalt, beryllium and silver in sea water prior to their determination by inductively coupled plasma-mass spectrometry. The optimum experimental conditions such as pH, sample flow rate and volume of eluents were investigated. The concentration factor of at least 300 for analytes of interest in sea water and separation of matrix components can be achieved. The recommended method has been applied for the determination of trace elements in coastal sea water. The results indicated that the recovery ranged from 91% to 107%, and the relative standard deviations were found to be less than 5% for trace elements at ng/L level.
