Significant, but usually insufficiently disclosed and analyzed, parameters of magnetophoresis of magnetoactive particles of liquid-dispersed media are the dynamic viscosity and density of the medium, as well as its temperature, which usually significantly affects the viscosity. The role of viscosity and density is analyzed using the example of such a variant of magnetophoresis as filtration magnetic separation (FMS). This role is reflected in the basic expressions for filtration efficiency and rate limiting. To legalize the role of temperature in these expressions, an approach was used to obtain phenomenological temperature dependences of the viscosity of a number of liquid media by identifying these dependences (or their characteristic sections), amenable to quasi-linearization in semi-logarithmic coordinates. Thus, the possibility of their description by functions of the logarithmic and exponential form is shown, and therefore - an alternative representation of expressions for the efficiency and limiting speed of FMS.
