Through st atic adsorption experiment , t he macroporous adsorption resins were screened . Based on dynamic adsorption st udy , t he sep aration condition was optimized . The result showed t hat t he L S803 resin had t he st rongest absorption cap acit y for delt amet hrin residue in apple j uice . The st atic absorption balance time of t he L S803 resin was 100 min . The optimized condition was obt ained as temperat ure 20 ℃, t he concent ration of apple j uice 110 g/ L , and flow rate 4 mL/ min .
