▎ 摘  要

NOVELTY - Adsorbent. The adsorbent is obtained by modifying metal-organic framework/reduced graphene oxide with a deep eutectic solvent, where the deep eutectic solvent is a choline chloride-levulinic acid deep eutectic solvent. USE - The adsorbent is useful adsorption of psychoactive substances including methamphetamine and/or amphetamine in aqueous environment for analysis of amphetamine and/or amphetamine in aqueous environment (all claimed). ADVANTAGE - The adsorbent has extremely strong selective adsorption for methamphetamine and amphetamine in the psychoactive substances, and the adsorption amount of methamphetamine and/or amphetamine can reach about 375 μg/g, which is a large adsorption amount. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for adsorption of psychoactive substances in an aqueous environment, comprises mixing and reacting the adsorbent with the psychoactive substance aqueous solution for adsorption, where the psychoactive substance is methamphetamine and/or amphetamine.
