Abstract:

This study reports on research results in the field of the neutralization process (weak acid–strong base) under the action of a rotating magnetic field. The main objective of this paper is to present the possibilities of this process application to obtain the mixing time. The results show that the applied magnetic field had a strong influence on the analyzed process. Enhancement of the mixing process under the action of the rotating magnetic field may be obtained using particles with magnetic properties. It is shown that the time, after which the equivalence point of the neutralization process is reached, may be considered a parameter to describe the mixing process. Based on the proposed definition of the mixing time, the dimensionless correlation for the relationship between the mixing number and the Reynolds number is presented. Furthermore, results for the realization of the neutralization process with the application of the rotating magnetic field and magnetic particles are also discussed.
