Abstract: A simple and sensitive method has been developed for the determination of cadmium in beverage by kelp centrifugation introduction graphite-furnace atomic absorption spectrometry after enrichment. The cadmium was fixed on finely divided as the complex with kelp was collected on a membrane filter by filtration under suction. then wash down the kelp used 0.3 mol/L hydrochloric acid from membrane filter paper and the centrifugation was directly subjected to the determination by graphite-furnace atomic absorption spectrometry. It is shown that the kelp are rinsed with 1 mol/L hydrochloric acid solution, Cd adsorption on the kelp is improved. When n = 5, standard deviation (SD) of these samples were from 0.0064 to 0.0022 and recoveries added were 97 % and 103 %,the results were comparatively satisfied.
