▎ 摘　　要

NOVELTY - The method involves taking a glassy carbon electrode as a working electrode. The glassy carbon electrode is soaked in graphene quantum point/Iy-cyclodextrin composite material solution. Volt-ampere value of a graphene quantum point/Iy-cyclodextrin composite film embellish electrode is determined. Color amine acid enantiomer solution and L/D-tryptophan solution are prepared in a beaker for identifying tryptophane enantiomer. The graphene quantum point/Iy-cyclodextrin composite film embellish electrode is dipped into the L/D-tryptophan solution for determining sweeping difference pulse. USE - Graphene quantum point cyclodextrin composite film embellish electrode preparing method for identifying tryptophan enantiomer. ADVANTAGE - The method enables realizing graphene quantum point cyclodextrin composite film embellish electrode preparing process in a simple manner, and protecting environment in an effective manner, and improving identification efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a graphene quantum point cyclodextrin composite film embellish electrode preparing method.
