Number of Applications Procedure Performed ZEN (%) in the Buffer (A) or the Eluent (B, C) ∑ (%)
1st application of the polymer A: After extraction with BBP 8.0 ± 0.3 99.8
B: After the 1st elution 85.8 ± 1.6
C: After the 2nd elution 6.0 ± 0.7
2nd application of the polymer A: After extraction with BBP 7.1 ± 0.2 98.3
B: After the 1st elution 84.8 ± 1.5
C: After the 2nd elution 6.4 ± 0.8
3rd application of the polymer A: After extraction with BBP 7.4 ± 0.4 -

A: Percent of ZEN (10 μM) remaining in 1.5 mL sodium acetate buffer (pH 5.0), after its incubation with 10 mg BBP for 40 min at 25 °C. B: Percent of ZEN recovered in the ethanol-water mixture, after the first elution from the polymer with 1.5 mL 50 v/v% ethanol for 10 min at 25 °C. C: Percent of ZEN recovered in the ethanol-water mixture, after the second elution from the polymer with 1.5 mL 50 v/v% ethanol for 10 min at 25 °C.
