| 英文摘要 | A procedure for the sequential determination of arsenite [As(III)] and arsenate [As(V)] based on electrochemical detection for As(III) and spectrophotometric detection for As(V) following ion chromatographic separation was developed. The color-developing system was based on the ion-association complex formed by heteropolymolybdoarsenic acid with bismuth in the presence of Triton X-100. Experimental conditions for electrochemical detection and color-developing conditions were optimized for As(III) and As(V), respectively. The optimal applied potential for electrochemical detection of As(III) was + 0.35 V and the wavelength for spectrophotometric detection of As(V) was 700 nm. By using an eluent of 2.0 mM sodium hydrogencarbonate-5.5 mM sodium carbonate with a 175 mu l sample loop for ion chromatographic separation, the detection limits, which are defined as the concentrations that give the peak intensity twice the baseline noise, are found to be 2.9 mu g/l for As(III) and 13 mu g/l for As(V), respectively. The spiked waste water samples were analyzed and recoveries were found to be 97.5-104% for As(III) and 93.5-103% for As(V), respectively. |
