PURPOSE : A manufacturing method of a magnetic a nanoparticle recovery device is provided to maintain concentration of a derive solution even a derived solution is diluted if a derived solution is dilled by a front osmosis membrane filtering process. CONSTITUTION : A magnetic a nanoparticle recovery device consists of a solution transfer pipe and a magnetic field applying unit. Through the solution transfer pipe, solution is transferred. The magnetic field applying unit is attaches and detaches magnetic nanoparticle onto the solution transfer pipe by selectively applying magnetic field. The magnetic field applying unit consists of a magnetic case attached to the solution transfer pipe, and magnetic particle(133) which is placed in the magnetic case(132).
