Preparation of a novel magnetic powder resin for the rapid removal of tetracycline in the aquatic environment

Magnetic powder resin Q150 with high specific surface area of 1074 m2/g was prepared by the membrane emulsification-suspension polymerization technique. Adsoption of tetracycline on the obtained sorbent Q150 was evaluted by using the granule resin (GR) XAD-4, the powder activated carbon (PAC) 1240AC and the granule activated carbon (GAC) HD4000 for comparison. It was found that Q150 had a larger adsorption capacity, faster kinetic and easier regeneration under alkaline condition. The results suggested that the powder resin (PR) Q150 would be a promising sorbent for removing antibiotics and even other organic micropollutants from the aquatic environment.
