Abstract: PURPOSE:To efficiently produce an electrically conductive polymer film contg. particles by dispersing particles in a generally used insulating polymer film and combining the polymer film with an electrolytically polymerized polymer to convert the polymer film into an electric conductor. CONSTITUTION:An insulating polymer film contg. dispersed particles is formed on the surface of a substrate electrode. This coated electrode as a working electrode is put in an electrolyte soln. contg. a monomer capable of forming an electrically conductive polymer film by electrolytic polymn. on the surface of an uncoated substrate electrode used as a working electrode. Electric current is then supplied to carry out electrolytic polymn. The polymer film as a dispersion medium for the solid particles is converted into an electric conductor and an electrically conductive polymer film contg. particles is produced.

Abstract: PURPOSE:To make rapid and simple measurement with a high sensitivity by measuring catecholamines by an electrochemical method having simplicity under the conditions under which an oxidizing enzyme and the substrate org. matter of this enzyme exist in a sample chamber. CONSTITUTION:The oxidizing enzyme and the substrate org. matter of this enzyme are made to exist in the sample chamber at the time of measuring the catecholamines in a sample soln. contg. catecholamines of biotissue extracts, etc., such as dopamine, adrenalin, and noradrenalin. The electrode response with the catecholamines is then chemically amplified and the electrode response with ascorbic acids, etc., which disturb the measurement are not chemically amplified. The catecholamines are rapidly and easily measured with the high sensitivity by the electrochemical method which consists in impressing the potential necessary and sufficient for the electrolytic oxidation of the catecholamines to the electrode in this state and measuring the concn. of the catecholamines from the electrode current and has the simplicity.

Abstract: PURPOSE:To obtain an electrodeposited thin film of a phthalocyanine compound useful as a catalyst and an organic electronic material, by dissolving an octaalkoxyphthalocyanine compound in an organic solvent, dipping a conductor into the solution and electrifying the solution using the conductor as a working electrode. CONSTITUTION:A compound of formula (R is 1-18C alkyl; M is H2, Mg, Cr, Mn, Fe, Cu, Zn, Pb, etc.) is dissolved in an organic solvent (e.g. dichloromethane, DMF, etc.), a supporting electrolyte (e.g. LiClO4) is added to the solution and the mixture is filled in an electrolytic cell. A conductor (e.g. Pt, graphite, etc.) and a counter electrode are inserted into the mixture to effect the electrolytic deposition of a thin film of a phthalocyanine compound on the conductor. The process enables the production of a thin film free from binder and having freely controllable thickness. The thin film has uniform composition and sufficiently high adhesivity to the substrate. The compound becomes insoluble in solvents other than concentrated sulfuric acid by the electrolytic deposition.

Abstract: PURPOSE:To easily discriminate the anion contained in an aqueous solution, by applying potential scanning to a polydivinyl ferrocene membrane in the aqueous solution to measure the peak potential of a current-potential curve. CONSTITUTION:A conductor (acting electrode) 3 covered with a polydivinyl ferrocene membrane, a reference electrode 4 and an opposed electrode 5 are inserted in an aqueous electrolyte solution 2. Next, a potentiostat 6 and a function generator 7 are combined to perform potential scanning at a predetermined scanning speed. The obtained current-potential curve is recorded on an X-Y recording needle, and anode peak potential and cathode peak potential are read. Since said potentials show different values by the anion contained in the aqueous solution, the kind of the anion contained in an unknown specimen can be discriminated from said anode and cathode peak potentials.
