The invention relates to a separation and recovery method of rare earth and an apparatus employing the method to raise rare earth recovery purity. The separation method includes the steps as follows: first, polymers with carboxyl groups and organic matter with amino groups are added to a solution containing Dy and other rare earth, condensation product with higher Dy concertration than other rare earth is produced; and second, alkali is added to the condensation product obtained by filtration, dysprosium hydroxide precipitate is obtained, and the solution containing polymers with carboxyl groups and organic matter with amino groups is obtained.
