Abstract
The activated MIL-53-Al powder is used as a solid-phase extraction column filler and is used for enriching trace artificial sweeteners in water samples and food samples in the environment, simulation calculation and adsorption tests show that the activated MIL-53-Al powder can efficiently adsorb various artificial sweeteners, and the content of the trace artificial sweeteners in the water samples and the food samples in the environment is reduced. And the adsorbed artificial sweetening agent is easily separated from the activated MIL-53-Al powder in the subsequent elution process, so that the purpose of efficiently enriching the artificial sweetening agent is achieved, and the subsequent detection precision of the artificial sweetening agent is further improved.
