The coordination properties to ward Cu(II) and Fe(III) of 1-N-(1'-hydroxy- 2c- naphthoyl)-1,4,7,10-tetraazacyclododecane and 1,7-bis-N,N-(1c- hydroxy-2c- naphthoyl)-1,4,7,10-tetraazacyclododecane have been studied by means of UV-Vis spectroscopy. The stability constants of copper and iron complexes with those compounds were determined. Synthesis of modified silica gels was presented. Selective preconcentration of Cu(II) and Fe(III) on modified stationary phases was investigated.
