外文摘要：This work presents a disposable bismuth-antimony film electrode fabricated on screen-printed electrode (SPE) substrates for lead(II) determination. This bismuth-antimony film screen-printed electrode (Bi-SbSPE) is simply prepared by simultaneously in situ depositing bismuth(III) and antimony(III) with analytes on the homemade SPE. The Bi-SbSPE can provide an enhanced electrochemical stripping signal for lead(II) compared to bismuth film screen-printed electrodes (BiSPE), antimony film screen-printed electrodes (SbSPE) and bismuth-antimony film glassy carbon electrodes (Bi-SbGC). Under optimized conditions, the Bi-SbSPE exhibits attractive linear responses towards lead(II) with a detection limit of 0.07?μg/L. The Bi-SbSPE has been demonstrated successfully to detect lead in river water sample.
