摘要：

A capsule with catalysis activity for pesticides degradation as well as adsorption activity for corresponding product elimination was developed by a simple one-step polymerization method based on molecular imprinting technology. More importantly, the absorption behavior of the capsule was investigated in detail by an in situ method, which showed that the capsule could absorb product more quickly.
