Clark Oxygen Electrode

The kinetics of the laccase-catalyzed oxidation of model lignin components by oxygen has been studied. It has been shown that in natural lignis the fragments containing guaiacyl groups are enzymatically oxidized without cleavage of the ether bond in the methoxy group. The enzyme has been immobilized by entrapping in polyacrylamide gel and also by covalent attachment to the surface of alkylamine glass. Immobilized laccase was used for the construction of sensors with the Clark oxygen electrode; such sensors can be employed for the determination of the content of lignin-like and phenolic compounds in waste waters.

Method Of Determination

The minimum on the polarographic curves for Bi(III) reduction in HCl solutions occurring when small amounts of surfactants are present can be used for their quantitative determination. The form of the polarograms was examined with respect to the concentration of the surfactant, and the range of concentrations in which the method of determination can be used is discussed.
