Abstract：A new determination method of Fe and Fe without separation was established by flow injection (FI) knitted reactor (KR) online preenrichment and flame atomic absorption spectrometry (FAAS). The total content of Fe and Fe was firstly determined by FAAS. Then, based on the difference of enrichment factor (EF) after FIKR preenrichment and FAAS detection, the concentration ratio between Fe and Fe was obtained. Consequently, the content of Fe and Fe could be calculated. The influencing factors on determination, including the type, flow rate and concentration of complex reagent, system pH, sampling time and flow rate, and the type and flow rate of eluent, were studied. The optimal experimental conditions were obtained. The proposed method was applied to the determination of actual water sample, and the results were consistent with those obtained by ophen spectrophotometry. The relative standard deviations (RSD, n=11, %) were less than 3.8 %.
