▎ 摘  要

NOVELTY - A forest terbutaline sulfate electrochemical sensors constructing method involves pretreating glassy carbon electrode by polishing electrode with aluminum oxide powder and distilling the electrode with water. Graphene carbon nanotube dispersion liquid is prepared by mixing multi-wall carbon nanotubes and drying in ultrasonic dispersion to obtain graphene carbon nanotube dispersion liquid. Preparing multi-walled carbon nanotubes modified electrode by dispersing graphene walled carbon nanotube dispersion and drying under an infrared lamp to obtain carbon nanotubes modified electrode. USE - Method for constructing forest terbutaline sulfate electrochemical sensors. ADVANTAGE - The method enables constructing forest terbutaline sulfate electrochemical sensors with better electro-catalytic performance and high terbutaline sulfate detection sensitivity. DETAILED DESCRIPTION - A forest terbutaline sulfate electrochemical sensors constructing method involves pretreating glassy carbon electrode by polishing upper layer of electrode with aluminum oxide powder and distilling the electrode with water. The electrode is cleaned using secondary ultrasonic cleaning for 3 minutes. The glassy carbon electrode is cleaned with sulfuric acid and the electrode is rinsed with water. Graphene carbon nanotube dispersion liquid is prepared by mixing multi-wall carbon nanotubes, solution nitric acids and hydrochloric acid, and refluxing for 12 hours, adjusting pH of sodium hydroxide to 6-8, washing after centrifuging and drying, weighing and treating with 2.5mg wall carbon nanotubes, drying in ultrasonic dispersion for 30 minutes to obtain graphene - multi-walled carbon nanotube dispersion liquid. Preparing multi-walled carbon nanotubes modified electrode by dispersing graphene in 4 ml walled carbon nanotube dispersion, drying in ultrasound for 15 minutes, cleaning glassy carbon electrode, drying under an infrared lamp to obtain multi-walled carbon nanotubes modified electrode.
