Polarograph

Polarography is an analytical method that is used to determine the concentration of various substances in a solution. It is based on the use of a polarograph - a device that allows you to measure the current passing through a solution when it comes into contact with an electrode.

A polarograph consists of two main parts: a polarographic cell and a polarographic sensor. A polarographic cell is a chamber that contains a solution containing the analyte. The polarographic sensor is an electrode that is located inside the chamber and is in contact with the solution.

When the polarograph is turned on, the electrode begins to move along the solution, and the current passing through the cell changes. This change in current depends on the concentration of the analyte in the solution.

Polarography is widely used in scientific research and industry to determine the concentration of substances such as metals, ions, organic compounds, etc. It can also be used to control the quality of food, water and other materials.

One of the advantages of polarography is its high sensitivity and accuracy. In addition, it does not require the use of chemicals and is environmentally friendly. However, to obtain accurate results, it is necessary to correctly configure the polarograph and select the optimal operating mode.

In conclusion, polarography is an important analysis technique that is widely used in various fields of science and industry. It allows you to quickly and accurately determine the concentration of various substances in solutions, making it an indispensable tool in scientific research and production processes.

Polarography is a classical method for studying the electrochemical behavior of substances. The method is based on Faraday's law, which describes the change in potential in electrolytes when an electric current flows - direct or reverse. The source of direct current is a polarizable electrode. A cathode, used as a source of electrons, and an anode are connected to this electrode.
