Abstract

The invention relates to the technical field of electrochemical sensors, in particular to a card type potassium ion sensor and a method for preparing the card type potassium ion sensor. The sensor comprises a base plate (1), two potassium ion selective electrodes (2) arranged on the base plate (1) in parallel, an insulation layer (3) and a salt bridge (4). Each potassium ion selective electrode (2) comprises an electrode substrate system (20), an electrolyte layer (21) and a potassium ion sensitive membrane (22), wherein each electrode substrate system (20) is composed of a reaction electrode (201), a contact electrode (202) and a conductive wire (203), the reaction electrodes (201) and the contact electrodes (202) are arranged on the base plate (1), and the conductive wires (203) are connected with the reaction electrodes (201) and the contact electrodes (202). The electrolyte layers (21) are arranged on the reaction electrodes (201) of the electrode substrate systems (20), and the potassium ion sensitive membranes (22) surround the electrolyte layers (21). The sensor is convenient to carry, and has the advantages of being easy to operate, rapid in response and stable in work.

Description

technical field

[0001] The invention relates to the technical field of electrochemical sensors, in particular to a card-type potassium ion sensor and a preparation method thereof.

[0002] Background technique

[0003] Potassium is an indispensable constant element in the human body, and the average adult body contains about 150 grams of potassium. The role of potassium in the human body is to maintain the normal function of nerves and muscles, to maintain the normal osmotic pressure and acid-base balance of the body, to participate in the metabolism of sugar and protein, and to ensure the normal function of neuromuscular. Potassium deficiency in the human body can lead to acid-base balance disorders, metabolic disorders, and muscle weakness. therefore. The detection of potassium ions has a wide range of applications in many fields such as medicine, biochemistry, pharmacy, chemical industry, environmental protection and food, especially the detection of potassium ions in ...
