Özet

A column filled with Amberlite XAD-1180 resin was examined in order to test its suitability for extracting inorganic complexes of Cu, Cd, Pb, Bi, Ni, Fe, Mn and Co from sulfuric, nitric or hydrochloric acid solutions containing iodide, thiocyanate or their mixtures. The proposed procedure was applied to the determination of Cu, Cd, Pb and Bi in pure zinc metals by flame- or graphite furnace-atomic absorption spectrometry with good results, such as recoveries greater than or equal to 95%, relative standard deviations less than or equal to 6% (n=10) and detection limits less than or equal to 0.200 mu g cm(-3).
