Eu3+ carbon dots for specific recognition and degradation of tetracycline
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.
