NONSTATIONARY MASS-TRANSFER UNDER PARTICLE MAGNETOPHORESIS IN DILUTEDFERROCOLLOIDS

Nonstationary mass transfer under nanoparticle magnetophoresis in dilu ted ferrocolloids is experimentally investigated. Measurements perform ed by using the real time holography technique indicate a difference b etween the concentration boundary layer parameters found in the experi ment and those calculated by using the approximation of nonstationary magnetodiffusion of colloidal particles. We suppose that the final sta tionary concentration distribution in the boundary layer is caused by a magnetic convection. Approximative calculations of concentration mag netic convection give the mass transfer relaxation time close to the e xperimentally determined one.
