▎ 摘　　要

NOVELTY - The method involves preparing titanium dioxide-graphene composite material. Graphene dispersion liquid is obtained. Titanium (IV) fluoride (TiF4) solution is obtained. Ethanol washing process is performed by deionized water. The titanium dioxide-graphene composite material is dispersed in organic solvent. A titanium dioxide-graphene/screen print electrode is formed as a p-chlorophenol detecting electrode. Circulation voltammetry scanning acid solution is prepared. Scanning speed of the circulation voltammetry scanning acid solution is about 10 to 100mV/s. USE - P-chlorophenol titanium dioxide-graphene/screen print electrode preparing method. ADVANTAGE - The method enables effectively realizing p-chlorophenol titanium dioxide-graphene/screen print electrode preparing process in a simple and easy manner to obtain carbon material preparation sensitive substance with titanium dioxide-graphene/screen print stable property and wide range of applications. The method enables improving sensitivity and reproduction quality, reducing preparing cost and coating titanium dioxide graphene surface to obtain a high-sensitive film by realizing drip-painting process. The method enables effectively improving detection limiting performance of a sensor and determining different environment samples. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a p-chlorophenol titanium dioxide-graphene/screen print electrode.
