2-Nitrofluorene is an environmental pollutant that binds covalently to haemoglobin after nitroreduction and successive N-hydroxylation. these haemoglobin adducts can be cleaved in vitro by mild base-catalysed hydrolysis. For the enrichment of arylamines from the aqueous hydrolysate, an extraction procedure with an organic solvent is widely used. Because of the formation of a thick emulsion layer between the aqueous and organic solvent layers, the extraction is laborious and inefficient. The use of Amberlite XAD2 provides a simple extraction procedure yielding a recovery of ca. 70%. Calibration curves in haemoglobin solution were prepared with a correlation coefficient of 0.998 (n = 12). The inter-day coefficient of variation amounted to 14%.
