Abstract

　本発明は溶液中に含まれるヒ素等の有害物質を精度良く検出するための電気化学的分析方法を提供することを目的とする。被測定電解質溶液中に作用電極と対電極とを配置し、作用電極に負電位を与えて、前記電解質を前記作用電極の表面に電着させて電着物質を形成し、次いで、前記作用電極の電位を正電位方向にスイープして前記電着物質を前記溶液中に溶出させると共に、電位変化に対する電流変化を検出して前記被測定電解質溶液中に電解質として溶解している被測定物質を分析する電気化学的分析方法において、作用電極としてホウ素をドープした導電性ダイヤモンド電極又は該電極の表面に金を付着した電極を使用する電気化学的分析方法。
