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...
