1. An electrochemical cell for the detection of phenol and phenol related compounds which comprises:

  • a cathode compartment containing a cathode in an electrolyte solution containing ferrocyanide ion;

    an anodic compartment containing an anode formed by coating a gel containing a phenol or phenol related compound oxidizing enzyme onto the conductive substrate of said anode immersed into an electrolyte solution containing ferrocyanide ion;

    means for directing oxygen into said electrolyte solution in said anodic compartment;

    means for maintaining a conductive relationship between anodic and cathodic compartments; and

    means connected to said anode and cathode for measuring the potential of the oxidation of said phenol or phenol related compound.
