For determination of pyruvic acid, we used the ferrocene as an electron transfer mediator and pyruvate oxidase as a catalyzer, and had a systemic research for the immobilization of ferrocene and enzyme on the gold electrode. At last, a pyruvic acid biosensor with good stability and activity of electrochemistry and biocatalysis was constructed. There are two aspects of contents in the paper. The first step, we had an in-depth research for the immobilization of ferrocene on the gold electrode, and fabricated a modified gold electrode by glutaric dialdehyde cross-linked egg white as the matrix of ferrocene immobilization.

Thinking of presenting problems, this research mainly studied some solid base catalysts which own higher catalysis ability and longer lifetime. Then, the phase diagram and equilibrium data of oil-alcohol-biodiesel-glycerol multiphase system were measured because the biodiesel producing process lacks of thermodynamic data.Based on a double-membranes theory and the thermodynamic data, a kinetic model was proposed. In addition, a mult-step extraction process was proposed to dispose the jatropha curcas l oil with high acid value in order to decrease the acid value. Then, a new technology of biodiesel producing using solid base as a catalyst was developed. The study objects and results are as follows.
