Abstract

Abstract: Although fluorescence sensors based on carbon dots (CDs) have been developed widely, multicomponent detection using CDs without extra and tedious surface modification remains a challenge. Here, the crude carbon nanoparticles (CPs) as a fluorescence sensor were prepared through one‐pot hydrothermal process using orange peel as the precursor. The method was simple, rapid, economical, and eco‐friendly given that such extra steps as dialysis and lyophilization were not required. By adding ethanol into the reaction solvent, the fluorescence properties of orange‐peel‐derived CPs as well as their sensitivity of detecting Fe 3+ with a limit of detection of 0.25 μM were improved. Additionally, orange‐peel‐derived CPs could be used as a fluorescence sensor for detection of ascorbic acid (AA) with a LOD of 5 μM. More importantly, the proposed fluorescence methods were successfully used to qualitatively and quantitatively analyze Fe 3+ and AA in real samples. Recovery of Fe 3+ from tap water was within the range 97.2–105.4%. Conversely, recovery of AA from vitamin C tablets and orange juices laid within the ranges 97.7–99.3% and 93.2–97.6%, respectively. Abstract : Highlights An efficient fluorescence sensor for detection of Fe 3+ and AA is presented. The sensor is based on crude orange‐peel‐derived CPs. The fluorescence properties of CPs are optimized by simply adjusting the composition of reaction solvent. The preparation method of the sensor is effectively simplified and eco‐friendly.
