微波辅助法一步合成荧光碳点用于水中三价铁离子的检测
One-pot Microwave-assisted Synthesis of Passivated Fluorescent Carbon Dots for Fe(Ⅲ)Detection
摘要
Abstract
Carbon dots(CDs)were synthesized through one-pot microwave-assisted synthesis method using citric acid as carbon source,glycerol as solvent and passivation agent.The obtained CDs have uniform size and good dispersion.The proposed synthesis method is rapid,simple and eco-friendly.The CDs were applied to detecting Fe3+in practical water samples based on fluorescence(FL)quenching mechanism with a linear range of 5—50 μmol/L,a detection limit of 2.16 μmol/L and the recoveries of 96.8%—106.0%,which showed good feasibility in detection of Fe3+in practical water samples.关键词
