Abstract
A method for magnetically assisted extraction of a target substance from an aqueous solution containing a plurality components includes mixing a surfactant and functional magnetic particles having affinity for the target substance into the aqueous solution containing the target substance so as to bind the target substance to the functional magnetic particles and form a particle-containing single-phase aqueous surfactant solution. The particle-containing single-phase aqueous surfactant solution is transitioned to a two-phase state, a first particle- and surfactant-containing disperse phase being formed within a surrounding second phase. The first particle- and surfactant-containing disperse phase and the surrounding second phase are separated using a magnetic field. The first particle- and surfactant-containing disperse phase are separated.
