Synthesis and Properties of Oxidative Modified Satium Lignosulfonate/ Graphene Quantum Dots Composites
摘要
Abstract
Oxidative modified sodium lignosulfonate/graphene quantum dots (HSL/GQDs) composites was synthesized using by products of the sulfite-pulping procedure (sodium lignosulfonate) and citric acid.Fluorescence spectroscopy, UV-vis spectra, and TEM were used to investigate the optical properties, structure and ions detection of the prepared HSL/GQDs.The HSL/GQDs exhibited strong fluorescence, which present two times high intensity (F0) than that of the free GQDs. The experimental results showed that HSL/GQDs could detect Fe3+ with high sensitivity and specificity according to the change of the fluorescence intensity. The Fe3+ concentration and the fluorescent quenching intensity of prepared HSL/GQD safter adding Fe3+ presented a good linearity in range of 10-500 μmol/L, with alinear equation of F/F0=0.851 12-0.001 11C (Fe3+) (R2=0.99) .关键词
