摘要
Peak of AgMT is formed on m-AgSAE from MT in alkaline media. The height of this peak is proportional to the MT concentration in range 37- to 301 ng /ml and can be increased with accumulation. In ammonia solution with Co(III) salt, apart from usual Brdicka response at - 1400 mV another, more positive catalytic system is observed, when formation of AgMT is allowed. This phenomenon has been confirmed by elimination voltammetry.
