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
