High polymer material separation method based on magnetic-Archimedes principle

Disclosed is a high polymer material separation method based on a magnetic-Archimedes principle. The method comprises the steps that (1) a medium solution is determined according to the difference of the densities of mixed high polymer samples; (2) the mixed high polymer samples are washed with a washing agent; (3) the mixed high polymer samples are placed in the medium solution; (4) the medium solution is placed in a magnetic suspension detection device, wherein the magnetic suspension detection device comprises two square magnets with same poles arranged in a face-to-face mode; and (5) the high polymer samples with different densities are layered in the medium solution, the different samples are taken out in a layered mode, and separation is accomplished. Compared with the prior art, the method has the beneficial effects that a brand new high polymer material separation method is provided, operation of the required device is easy, the cost is low, the measurement result is easy to observe, the measurement accuracy is high, and the automation of the method is easy to achieve.
