Sulfur Fine Particles as Stationary Phase for TLC/FTIR Analysis
摘要
Abstract
In situ thin-layer chromatography-Fourier transform infrared spectroscopy ( TLC-FTIR ) technique has tremendous potential in the analysis of complex mixtures. However, the progress in this technique was quite slow. The reason is that conventional stationary phase has strong absorption in FTIR spectrum and brings about severe interference in the detection of samples. This paper proposes to use sulfur fine particles, which is transparent in mid-infrared, as a new type of TLC stationary phase. Additionally, decreasing the particle size of sulfur is very important in TLC-FTIR analysis technique. By optimizing the experimental conditions, the sulfur particle with a size of 500 nm was prepared and the conventional TLC plate and the narrow TLC plate using the sulfur paticles as the stationary phase was prepared. TLC experimental results prove that the TLC plate can separate the mixture of rhodamine B and gentian violet successfully. FTIR analysis confirms that the FTIR spectra of the separated rhodamine B/gentian violet spots and rhodamine B/bromophenol blue spots are in good agreement with the FTIR spectra of pure rhodamine B, gentian violet and bromophenol blue.关键词
