Electrolytic tank for soil corrosion electrochemical experiment

The invention discloses an electrolytic tank for a soil corrosion electrochemical experiment. The electrolytic tank comprises an electrolytic tank body, a back-insert type antimony reference electrode, a back-insert type working electrode and a graphite auxiliary electrode, wherein a soil medium containing chamber is arranged in the electrolytic tank body and contains a soil medium, a first electrode chamber and a second electrode chamber are arranged on the two sides of the soil medium containing chamber respectively, the back-insert type antimony reference electrode is arranged in the first electrode chamber, the back-insert type working electrode is arranged in the first electrode chamber, and the graphite auxiliary electrode is arranged in the second electrode chamber. The back-insert type antimony reference electrode is adopted, the graphite electrode is used as the auxiliary electrode, and therefore the IR drop interference caused by soil resistance can be effectively reduced, the soil humidity in the electrolytic tank can be controlled unchanged within the range of 0-100 DEG C for a long time, the soil environment required by the experiment is kept, the electrolytic tank for the soil corrosion electrochemical experiment is convenient to detach and assemble, and the experiment can be rapidly conducted.
