英文摘要Iron oxide with different crystal phases (alpha- and gamma-Fe2O3) has been applied to electrode coatings and been demonstrated to ultrasensitive and selective electrochemical sensing toward heavy metal ions (e.g., Pb(II)). A range of Pb(II) contents in micromoles (0.1 to 1.0 mu M) at alpha-Fe2O3 nanoflowers with a sensitivity of 137.23 mu A mu M-1 cm(-2) and nanomoles (from 0.1 to 1.0 nM) at gamma-Fe2O3 nanoflowers with a sensitivity of 197.82 mu A nM(-1) cm(-2) have been investigated. Furthermore, an extended X-ray absorption fine structure (EXAFS) technique was applied to characterize the difference of local structural environment of the adsorbed Pb(II) on the surface of alpha- and gamma-Fe2O3. The results first showed that alpha- and gamma-Fe2O3 had diverse interaction between Pb(II) and iron (hydro)oxides, which were consistent with the difference of electrochemical performance. Determining the responses of Cu(II) and Hg(II) as the most appropriate choice for comparison, the stripping voltammetric quantification of Pb(II) with high sensitivity and selectivity at gamma-Fe2O3 nanoflower has been demonstrated. This work reveals that the stripping performances of a nanomodifier have to be directly connected with its intrinsic surface atom arrangement.
