  • Tungsten and molybdenum in seawater can be sensitively and accurately determined by the polarographic catalytic wave.In a supporting electrolyte containing HCl-benzilic acid-Nad, tungsten has a clear and stable catalytic wave.Then, the peak current of molybdenum increases as KClO3 is added into the above medium.The sensitivity of the proposed method is 5×10-2 M for W and 6×10-10 M for Mo, respectively.
    This method is an extremely quick, sensitive one and is suitable for the analysis of various kinds of water.
