Sodium nitrite, as a food additive, is internationally recognized as a first-class carcinogen.To investigate the effect of a high-voltage pulsed electric field on the adsorption characteristics of sodium nitrite on wheat bran, a high-voltage pulsed electric field was used to treat wheat bran, and the kinetics and thermodynamic characteristics of wheat bran adsorption of sodium nitrite were analyzed.Results showed that the adsorption of sodium nitrite by wheat bran reached adsorption equilibrium after 120 minutes, and the pseudo-second-order kinetic equation and Freundlich model could better describe the adsorption process, indicating that the adsorption process involved both physical and chemical adsorption.The reaction of wheat bran adsorbing sodium nitrite was non-spontaneous, and increasing temperature increased the adsorption quantity and rate of wheat bran for nitrite, which promoted the adsorption quantity of wheat bran for sodium nitrite.As the electric field strength increased from 10 kV/cm to 40 kV/cm, the adsorption quantity and rate of wheat bran for sodium nitrite increased by 10.91% and 12.82%, respectively.However, when the electric field strength increased from 40 kV/cm to 50 kV/cm, the adsorption quantity and rate of wheat bran for sodium nitrite decreased by 7.46% and 16.45%, respectively.Therefore, the pulsed electric field of 40 kV/cm can be applied to improve the adsorption capacity of wheat bran for sodium nitrite, and the result can provide theoretical guidance for the comprehensive utilization of wheat bran.
