GOLD NANOPARTICLE CONTAINING CARBON THIN FILM ELECTRODE FOR ELECTROCHEMICAL MEASUREMENT AND METHOD OF ELECTROCHEMICALLY DETECTING ARSENIC ION USING ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a gold nanoparticle containing carbon thin film electrode having conductivity sufficient as an electrode and electrode catalytic activity excellent to arsenic, and method of simply manufacturing the same.SOLUTION: A carbon thin film electrode for electrochemical measurement for detecting arsenic ions by an electrode reaction on the basis of reduction deposition and oxidation elution in a solution to be measured is constituted of fine crystalline domains having an spbond and an spbond mixed together in a bond form between carbons, thereby has a potential window in a range wider than these of a graphite carbon electrode and a glassy carbon electrode and uniformly includes gold nanoparticles.SELECTED DRAWING: None
