摘　　要：为探索含新农抗702的HP-10大孔树脂的解吸及树脂再生的适宜条件,采用静态、动态方式对树脂进行洗脱;采用生物学法(管碟法)对树脂洗脱液中的残留物进行检测。结果表明,静态解吸时乙醇能够使含新农抗702的大孔HP-10树脂一次性解吸率达到90%;动态解吸时洗脱峰比较集中便于后续浓缩;通过比较再生前后树脂吸附的吸附性能发现,树脂基本再生完全,且再生方法简便,可使树脂重新获得吸附性能,故可反复使用,达到节约原料的目的。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.
