SH709 automatic mercaptan and sulfur measuring instrument using
potential titration method measurement principle.
The H2S-free sample was dissolved in isopropanol solvent of sodium
acetate, and potentiometric titration was carried out with standard
solution of silver alcohol nitrate. The pH glass electrode was used
as reference electrode, and the mercaptan sulfur electrode was used
as indicator electrode. The potentiometric spike between the two
electrodes indicated the end point of titration.
The mercaptan sulfur precipitates to silver mercaptan during
titration.
SH709 mercaptan and sulfur measuring instrument conforms to GB/T
1792, ASTM D3227 and other standards.
It is suitable for the determination of mercaptan sulfur in jet
fuel, gasoline, kerosene and light diesel oil without hydrogen
sulfide. The determination of mercaptan sulfur has important
significance in the evaluation of odor of jet fuel, gasoline,
kerosene and light diesel oil, the adverse effect on rubber parts
of fuel system and the corrosion of fuel system.
