In this work, for the first time, we report an efficient, simple strategy for synthesizing active camptothecin (CPT) derivatives in water. A novel macroporous adsorption resin-supported gold nanoparticle (MAR-AuNP) was first in situ prepared in water. The resulting MAR-AuNPs swell in water and were applied not only as an efficient adsorbent for hydrophobic CPT molecules, but also as a catalyst ...
The adsorption kinetics of the selected macroporous resin was studied by contacting 50 mL of crude exaction solution (pH 2.5, initial concentration = 639.14 mg/L) with a preweighed amount of hydrated resins (equal to 0.5 g of dry resin) on a shaker (100 rpm) at 25 °C.
