The Study Of Poly [N (3 Ferrocene Acetamino Propyl Pyrrole] Film Modified Glucose Electrode, Chengyun Tian, Jing Chen, Li Zhang
The Study Of Poly [N (3 Ferrocene Acetamino Propyl Pyrrole] Film Modified Glucose Electrode, Chengyun Tian, Jing Chen, Li Zhang
Journal of Electrochemistry
A poly [N (3 ferrocene acetamino propyl pyrrole)]film modified electrode was fabricated and studied by cyclic voltammetric method. The result shows that the modified electrode can give stable redox peaks of ferrocene, and an obvious catalytic peak due to glucose; This modified electrode was used to tabricate a glucose sensor which operates at +0.2 V, so that the ascorbic acid or uric acid doesn't affect the accuracy detection of glucose concentration. The sensor has a linear range of 0.1～10 mmol/L glucose, which the period of long term stability and response time of the sensor are about ten days and 2 …

Study On The Preparation, Properties And Applications Of The Polymer/Graphite Composite Electrode, Guohua Chen, Jinrui Xu
Journal of Electrochemistry
The graphite AS composite electrodes, which show high electric conductivity, high mechanical strength and operationl stability, were prepared by filling and extruding the AS copolymer with graphite powder. It exhibited a substantial hydrogen overvoltage and small residual current in different electrolytes, as compared with glassy carbon electrode. The electrode was applied to the determination of traces of Pb 2+ in mineral water, Ag + in waste water and In 3+ , Cu 2+ , Pb 2+ , Cd 2+ in zinc ore, and showed high stability, reproducibility and selectivity. Owing to the existence of abundant polar functioal groups on the …

The Electrochemical Behavior Of C￣(60)-Chemically Modified Poly(N-Vinylcarhzole)In 1 Mol/L Liclo_4-Thf Solutions, Yu Chen, Zuen Huang, Ruifang Cai, Fupin Zhang
Journal of Electrochemistry
The electrochemical behavior of C￣(60)-PNVC copolymer in 1 mol/L LiClO_4-THF solutions has been studied by cyclic voltammetry.The results demonstrated that there are considerable differences of electronic structure between PNVC (Poly (N-vinylcarbazole )) and C￣(60)-PNVC copolymer, this being consistent with the ESR results and the oxidstion-reduction activarion of pure PNVC by C￣(60)-chemical modification. In the potential region,1.3V～-3.5V,five steps,0. 90V/0.60V,0.20V/0.00V,-1.05V/-1.30 V,-1.25V/-1.75 V,-2.00V/-2.50V, of oxidation/reduction proceases were indicated in the cyclic voltammetry for pure PNVC,whereas seven steps,0.20V/0.20V,-0.30V/-0.50 V,-0. 60V/-0.60 V,-0.80V/-1. 10 V,-1.95V/-2. 10 V,-2. 50 V/-2. 70 V,-3. 00V/-3. 00 V, of oxidation/reduction processes for the C￣(60)-PNVC copolymer were observed under the idenrical …
