A flow-injection on-I& adsorption precontentration flame atomic absorption spectrometric system for the detenninatian of copper was developed. The copper d~eth~ldith~~arba~ate chefate was adsorbed on the walls of a PTFE knotted reactor. The sorbed species was eluted by isobutyl methyl ketone at a fl
ment factor of 47 in comparison with direct injection of 45 lL aqueous solution was obtained at a sampling frequency of 31 h โซ1ืโฌ . The detection limit (3 r) was found to be 2.8 ng L โซ1ืโฌ . The precision was 3% relative standard deviation (RSD) at the 0.2 lg L โซ1ืโฌ level (n โซืกโฌ 11). The results obta
