Paper-based electrolytic cell for electrochemical detection, manufacturing method thereof, and three-electrode system

Abstract

The invention discloses a paper-based electrolytic cell for electrochemical detection. The paper-based electrolytic cell comprises filter paper, wherein a closed carbon powder region is formed on the filter paper; and a region encircled by the carbon powder region serves as an electrolytic cell region. The invention also provides a manufacturing method for the paper-based electrolytic cell. The method comprises the following steps of: making a pattern of the carbon powder region on a computer; printing the carbon powder region on the filter paper by a laser printer with resolution of more than or equal to 300 dpi; and heating the filter paper on which the pattern is printed by a heating device at the temperature of between 120 and 180 DEG C for 60 to 300 minutes, and thus obtaining the paper-based electrolytic cell. Equipment for processing the paper-based electrolytic cell for the electrochemical detection is simple, can be implemented in a common laboratory, is low in manufacturing cost, and can be manufactured easily and quickly; the volume of a required sample is only 1 to 100 microliters; and the paper-based electrolytic cell has a wide using range and a small volume, is portable, meets the requirement of portable electrochemical detection, and is discardable.

Description

technical field [0001] The invention belongs to the field of electrochemistry, and in particular relates to a paper-based electrolytic cell for electrochemical detection, a manufacturing method thereof and a three-electrode system. Background technique [0002] Electrochemical detection refers to the application of electrochemistry to apply certain excitations to the research system, detect the corresponding signals, and analyze the experimental data. The so-called "three-electrode system" composed of electrolytic cell, working electrode, reference electrode and counter electrode is the key component for electrochemical detection. In the three-electrode system, the electrolytic cell is used to accommodate the working electrode, reference electrode and counter electrode, and provides a space for electrochemical reactions, which is the core of the three-electrode system. At present, electrolytic cells used for electrochemical detection are generally made of glass, polytetrafl...

AI Technical Summary

Problems solved by technology

At present, electrolytic cells used for electrochemical detection are generally made of glass, polytetrafluoroethylene, plexiglass (polymethyl methacrylate), polyethylene, polystyrene, epoxy resin, rubber and other materials. Special equipment, usually cannot be produced in the laboratory, and has a certain volume, so it is inconvenient to carry when going out for testing

In addition, the volume of solution required for electrochemical detection of the electrolytic cell made of the above materials is generally several to tens of milliliters. For the detection of samples with a small amount of sample, the use is limited.
