摘要："Development of a superior water pretreatment for monitoring the psychoactive substances in urban is requisite. Herein, a novel adsorbent with selective adsorption capacity for methamphetamine (MAMP) has been successfully designed through deep eutectic solvents (DES) as a modifier was used to regulate magnetic reduced graphene oxide/ZIF-67 (MGZ) composites. The DES, named as Choline chloride/Levulinic acid (LA), with high affinity towards MAMP, was screened by density functional theory (DFT). The DESs regulated MGZ to synthesize DES/MGZ, and the adsorption performances of diverse DES/MGZ were investigated by contrast experiment. The selective adsorption performances were investigated by selective experiment with multiple compounds. The MAMP adsorption amount of LA/MGZ was 365.96 & mu;g g-1, and enhanced 82.98% than MGZ (200.67 & mu;g g-1). The characteristic of pH-dependent occurred on the MAMP adsorption by LA/MGZ was attributed to the exfoliation of highly oxidized debris promote H-bonding and 7C-7C interactions between LA/MGZ and MAMP. Theoretical calculations in combination with characterization analyses illustrated the efficient recognition of LA toward MAMP was mainly dependent on the H-bonding interactions between carboxyl groups of LA and the -NH of MAMP, as well as the electron transfer from MAMP to levulinic acid. The proposed strategy in this work for designing DESs as a modifier to regulate the carrier materials based on DFT calculations to improve the selective adsorption ability would inspire more ideas in efficient water environmental treatment."
