Abstract

The theoretical description for 4-4´-dihydroxyazobenzene CoO(OH) – assisted electrochemical determination in mushroom pulp, food and biological liquids has been described. In this system, a squaraine dye is used as a Cobalt(III)oxyhydroxide stabilizer and electron transfer mediator. It is shown that, contrarily to the great part of the systems with cobalt (III) oxyhydroxide, this system will behave in a more stable manner, providing an efficient diffusion-controlled process. On the other hand, the oscillatory and monotonic instabilities, although possible, are caused by the double electric layer influences of either chemical or electrochemical stage.
