摘要

以柠檬酸、1.0代聚酰胺胺和氯化铕为原料,采用水热法合成了具有特异性识别四环素比例荧光探针,同时对四环素进行降解.结果表明,Eu3+-碳点(CDs)的量子产率为92%,具有抗干扰特性,可以特异性识别多种抗生素混合物中的四环素.c(四环素)=50 nmol/L~20 μmol/L,比例荧光强度和四环素浓度呈现良好线性关系,最低检测限为6 nmol/L.t=120 min,365 nm紫外光催化四环素的降解率为60%,经过5个循环的降解效率一致,具有优异的光催化稳定性.

Abstract

By employing citric acid,1.0G polyamide amine,and europium chloride as starting materials,a tetracycline-specific fluorescent probe was synthesized via hydrothermal method and was used to degrade tetracycline.The obtained Eu3+-CDs exhibited a remarkable quantum yield of 92%and demonstrated excellent anti-interference properties,enabling selective recognition of tetracycline in the presence of various antibiotics.The proportional fluorescence intensity was linear with tetracycline concentration in the range of 50 nmol/L to 20 μmol/L with a detection limit of 6 nmol/L.Under 365 nm UV light for 120 mins,the degradation rate of tetracycline reached up to 60%,while maintaining consistent photocatalytic efficiency even after five consecutive cycles,thus highlighting its exceptional stability.
