This study focuses on the favorable condition of desorption and regeneration of macroporous resin HP-10 loaded with new agricultural antibiotic 702(new anti-702).The resin HP-10 was eluted using static and dynamic methods and the residues from elution liquid were measured through biological method(cylinder plate method).The results showed that the desorption rate reached 90% by using ethanol as eluent in static desorption experiments.When dynamic desorption was employed,the elution peak would be more centralized,which will facilitate the subsequent concentration.By comparing the absorption properties of resins before and after regeneration,the results indicated that the resin could totally regenerate.This regeneration method is simple and could help resins regain its absorption capacity.Therefore,it could be recycled to save more raw materials.
