FLAMELESS ATOMIC-ABSORPTION SPECTROPHOTOMETRY OF COPPER BY THE INTRODUCTION OF CHELATING RESIN INTO CARBON TUBE ATOMIZER

A simple method for the determination of copper (ppb level) by the introduction of chelating resin into carbon tube atomizer was attemped. After the copper ion in the test solution (250 ml) has been adequately concentrated and 0.10 g of chelating resin (below 400 mesh) added, the resin was then separated from aqueous solution. Aliquots (10 μd) of resin-suspension, which was prepared by adding 5.0 ml of water to the above resin, were introduced into the atomizer. The optimum operating conditions are shown in Table 1. The calibration graph was linear up to 4.0 ppb of copper, and the relative standard deviation was 2.5% at 3.0 ppb level of copper. © 1979, The Chemical Society of Japan. All rights reserved.
