Electrochemical sensor for measuring sulfur content in diesel oil

The invention relates to an electrochemical sensor for measuring the sulfur content in diesel oil. The electrochemical sensor comprises a linear scanning voltammetry measuring system and a two-electrode or three-electrode electrochemical working system, the linear scanning voltammetry measuring system is connected with the two-electrode or three-electrode electrochemical working system; according to the two-electrode electrochemical sulfur sensor, a working electrode, an auxiliary electrode and ionic liquid-organic solvent mixed liquid form a two-electrode system; according to the three-electrode electrochemical sulfur sensor, a working electrode, an auxiliary electrode, a reference electrode and ionic liquid-organic solvent mixed liquid form a three-electrode system. The method for measuring the sulfur content in the diesel oil is more portable, quicker, quicker, more accurate and more efficient, and can effectively solve the problem that existing measuring technical equipment is expensive and inconvenient t
