Abstract

A carbon paste electrode capable of being heated comprises a glass pipe and a carbon paste groove, wherein the carbon paste groove is fixed on one end of the glass pipe. A heating lead and an electrode lead are arranged in the glass pipe, and the lower ends thereof are fixed by fixing glue to connect with the carbon paste groove. The carbon paste electrode has the characteristics that the structure is simple, the cost is low, the surface of the carbon paste can be easily rubbed down to provide a well reaction place, the carbon paste of the electrode has the renewable property, the most prominent characteristics is that binding agent and modifier can be alternatively selected according to detected targets in order to increase the sensitivity of the electrode, and the electrode has more stable performance under a variety of temperature, and can rapidly reach high temperature after short-time heating, thereby being used to study the electrode reactions under a variety of temperature.

Description

Can heat carbon paste electrode

Technical field:

The utility model relates to a kind of electrode, and especially a kind of carbon paste electrode that heats belongs to electrochemical field.

Background technology:

Carbon paste electrode (CPE) is to utilize the dag of electric conductivity and the binder of hydrophobic nature to be mixed and made into pastel, is coated in it on electrode bar then or inserts in the electrode tube and a class electrode of making.Temperature can influence the parameter in the galvanochemistry, and present carbon paste electrode is fixed owing to temperature, so range of application is very narrow.

Summary of the invention:

At above-mentioned the deficiencies in the prior art, the utility model provides a kind of carbon paste electrode that heats.
