Fluorescent adsorption material loaded with graphene quantum dots and preparation method of fluorescent adsorption material

The invention further discloses a fluorescent adsorption material loaded with graphene quantum dots and a preparation method of the fluorescent adsorption material, wherein the fluorescent adsorption material comprises PVA colloid, and the graphene quantum dots are embedded in the PVA colloid. The material has the potential of being applied to the field of heavy metal adsorption. A NGQDs-PVA composite film has excellent fluorescence and heavy metal adsorption performance, and the composite film emits blue fluorescence under the excitation wavelength of 360 nm. Compared with a traditional adsorbent, the composite film has a high selective adsorption effect (qe is equal to 317.35 mg/g, and T is equal to 40 DEG C) on Ag (I), and the fluorescence intensity can be obviously quenched after the composite film adsorbs Ag (I). 本发明还公开了一种负载有石墨烯量子点的荧光吸附材料及其制备方法，盖材料包括PVA胶体，所述PVA胶体中嵌入有石墨烯量子点。该材料具有应用于重金属吸附领域的潜力。NGQDs-PVA复合膜具有优异的荧光和重金属吸附性能，复合膜在360nm的激发波长下发出蓝色荧光。与传统吸附剂相比，它不仅对Ag(I)有较高的选择吸附效果(qe＝317.35mg/g，T＝40℃)，而且其荧光强度在吸附Ag(I
