Accelerated solvent extraction (ASE) has become a popular green extraction technology for different classes of organic contaminants present in numerous kinds of food and feed for food safety. The parameters affecting ASE efficiency and application advancement of ASE in the analysis of organic contaminants, natural toxins compounds as well as bioactive and(More)
A new molecularly imprinted solid-phase extraction (MISPE) procedure combined with liquid chromatography was developed for the simultaneous selective extraction and determination of ofloxacin (OFL) and lomefloxacin (LOM) in chicken muscle samples. The water-compatible molecularly imprinted microspheres (MIMs) were synthesized by aqueous suspension(More)
We studied the combination between seven kinds of drugs and the bovine serum albumin (BSA) using Methyl Green (MG) as fluorescent probe. These drugs were Streptomycin sulphate, Kanamycin sulfate, Gentamicin, Amikacin, Neomycin, Thiamphenicol and Florfenicol. And after reaction of these drugs, the fluorescence intensity of BSA had no obvious change. Research(More)
Dummy molecularly imprinted microspheres with danthron as template were synthesized and their performance was evaluated. Accelerated solvent extraction can rapidly and effectively remove template molecules from the microspheres. The microspheres were applied as a specific sorbent for solid-phase extraction of six anthraquinones from slimming tea, showing(More)
Interaction mechanism of cefoperazone sodium (CFP) and ofloxacin (OFX) with bovine serum albumin (BSA) at different temperatures by fluorescence spectrometry method was studied. Results showed that CFP or OFX could quench the fluorescence of BSA. The fluorescence would quench to a larger degree when OFX (or CFP) was added to the system of BSA-CFP (or(More)
A new data-driven predictive iterative learning control(ILC) is proposed for same category discrete nonlinear systems in this work. The controller design only depends on the input/output data of the system and does not need explicit mathematical model. More prediction information along the iteration axis is utilized in the learning control law to improve(More)
The interaction between Avelox and bovine serum albumin (BSA) was investigated at different temperatures by fluorescence spectroscopy. Results showed that Avelox could quench the intrinsic fluorescence of BSA strongly, and the quenching mechanism was a static quenching process with Förester spectroscopy energy transfer. The electrostatic force played an(More)
A simple and rapid ultrasound-assisted dispersive liquid-liquid microextraction method coupled with GC-flame ionization detection was developed for simultaneous determination of nine pyrethroids in domestic wastewater samples. An ultrasound-assisted process was applied to accelerate the formation of the fine cloudy solution using small volume of disperser(More)
In human physical conditions, the interaction of topiramate amyl cephalosporin cefotaxime (TACC) with bovine serum albumin (BSA) and the effects of coexistent drugs and metal ions were investigated by fluorescence spectroscopy. Results showed that the effect between TACC and BSA was static fluorescence quenching process, and the electrostatic attraction(More)
