| Abstract: | A method has been developed for the determination of cobalt with graphite furnace atomic absorption spectrometry (GFAAS) A higher pyrolysis temperature of 1550℃ and a higher sensitivity were obtained with palladium plus strontium as a mixed chemical modifier The proposed method was successfully applied to the determination of cobalt in tap water, well water and river water with a recovery range of 97 8%～101 3% |
