ROLE OF VISCOSITY AND TEMPERATURE FACTORS IN THE MAGNETOPHORESIS OF DISPERSED PHASE OF DIFFERENT LIQUID MEDIA

The role of rheological properties of a liquid dispersion medium, in particular, its dynamic viscosity determined by the temperature of the medium, in its magnetophoretic separation was investigated. The temperature dependences of the viscosity of a water and other liquids as well as their phenomenological approximations by logarithmic, exponential, and power functions in the working temperature ranges of these liquids are presented. The defi nition of the effi ciency of separation of a liquid dispersion medium with the use of magnetic fi lters by one of the indicated functions (a logarithmic one) and its testing by the corresponding experimental temperature dependence obtained for a low-concentration aqueous suspension, whose continuous medium is a water or an industrial condensate and disperse phase is formed by particles of a synthetic magnetite or ferroparticles, are considered.
