%X chemical analysis has evolved towards automation to satisfy the current requirements: fast analysis and certainty in the results. flow injection analysis (fia) is a way to reach automation. this work presents the necessary steps to obtain an optimized fia methodology for the determination of pb(ii) in water by classic methods. the result was a fia method to determinate pb with dithizone (chromogenic agent) dissolved in iso-propyl alcohol, using cethyltrimethylammonium bromide (ctab) to solubilize the complex. the main characteristics of the method were: injection sample volume 81.7 ¦Ìl, flow 8.0 ml/min, spectra acquisition time 1.4 s and linear range 1 to 40 mg l-1.
