This paper describes selenium determination based on se preconcentration in the imprinted polymer with subsequent detection online in HG-FAAS.drung the synthesis,seo2 is reduced to se. therefore,there are no MIP neither IIP in the present work.thus we denominated:AIP,i.e.,atomically imprinted polymer. For the optimization of analytical parameter Doehlert desight was used. The method presented limit of detection and limit of quantification 53 and 177 ng l ,respectively ,and linear range form 0.17 up to.The preconcentration factor(PF),consumptive index(CI) and concentration efficiency (CE)were 232;0.06 ml and 58 min respectively. THe proposed method was successfully applied to determine se in Brazil nuts,apricot ,white bean ,rice,flour and milk power sample.It was possible to do 12 analyzes per hour. Accuracy was checked and comfirmed by analyzing certified reference material ,and sample precision was satisfactory with RSD lower than 10 %.
