초록

n this study, the optimum conditions of working electrode with using organo-sericite was evaluated for the determination of As(III). The experimental results indicated that the peak currents of As(III) were increased as the size of sericite powders which were mixed in manufacturing for the organo-sericite electrode was decreased. The currents using polyether ether ketone (PEEK) as a support material for the electrode was considerably enhanced 12 times higher than that of the teflon material. The mixing ratios of raw materials for manufacturing the electrode were varied and the optimum ratio was obtained as the nujoil oil was 1.5 g and the organo-sericite was 15 wt%. Under the obtained optimum conditions, the peak currents were correlated well with the concentration of As(III) and it showed that As(III) levels down to 1 ppb were successfully analyzed. It concluded that the organo-sericite could be applied well to the determination of trace level of As(III) in aqueous solution.
