抄録
A simple and rapid determination method for trace amounts of copper and lead in water and rock samples by tungsten metal furnace atomic absorption spectrometry was investigated. Copper and lead were quantitatively collected on activated carbon impregnated with 1,2-cyclohexanediondioxime (AC-Dox) at pH 5.0 for copper and pH 8.0 for lead. The copper and lead collected on an AC-Dox were eluted with 1 mol dm-3 hydrochloric acid, and the absorbances of the eluents were measured at 324.8 nm for copper and 283.3 nm for lead, respectively. The detection limit (S/N=3) for copper was 0.013 µg/5.0 cm3 and that for lead was 0.075 µg/5.0 cm3. The relative standard deviations (n=5) were 2.0 - 4.0% for each metal.
