2023年9月1日 · Three-dimension excitation emission matrix fluorescence spectroscopy (3D-EEM) is used to identify the component variation of DOM after the electrochemical oxidation (EO). Liquid chromatograph mass spectrometer (LC-MS) is used to confirm the degradation pathway of TC whether spontaneous or electrochemical oxidation.

2024年6月1日 · The three-dimensional fluorescence spectroscopy (3D EEM) and UV scanning were performed to analyze TC mineralization. The 3D EEM spectra were analyzed using fluorescence region integral method, and the fluorescence regions formed by excitation and emission wavelengths were divided into five parts representing five different types of organic ...

In this study, tetracycline (TC) was selected as the representative pollutant, and corn straw biochar (pyrolyzed at 300 °C) was used as the adsorbent. Through batch experiments and microscopic...

2024年8月15日 · The study aimed to (1) examine the fluorescence substances of EPS under different TC concentrations using EEM-PARAFAC; (2) to utilize 2DCOS to detect the sequential changes in various constituents and functional groups in EPS combined with TC; and (3) to explore and intuitively visualize how the extracellular proteins couple with TC by using ...

2020年1月2日 · Tetracycline (TC) is one of the most used antibiotics and has accumulated in soil. Its adsorption behavior was studied, and the effect of dissolved organic matter (DOM) was evaluated based on the molecular interaction between DOM and TC. This paper is helpful for further understanding the mobility and bioavailability of TC in soil.

The excitation-emission matrix (EEM) and synchronous fluorescence (SyF) spectra of TC/HA solutions were recorded on a fluorescence spectrometer (Model Cary Eclipse, Varian, Santa Clara, CA, USA). The fluorescence spectrometer used a xenon excitation source, and slits were set to 5 nm for both excitation and emission.

In this work, hierarchically porous zero-valent copper (3DHP-ZVC) was designed and fabricated via 3D printing and applied as a catalyst for the degradation of tetracycline (TC) through heterog...

In this study, the roles of extracellular polymeric substances (EPSs) excreted by Pandoraea sp. XY-2 in the removal of tetracycline (TC) were investigated. In the early stage, TC in the...

2020年7月22日 · Photolytic degradation of tetracycline (TC) was investigated in mono- and binary solute systems of Ca (II) and humic acid (HA) under UVA light emitting diode (UVA-LED) light irradiation. TC photolysis proceeded via pseudo-first-order reaction kinetics.

Three-dimensional excitation–emission matrix (3D-EEM), synchronous fluorescence, two-dimensional correlation spectroscopy (2D-COS) and FT-IR (Fourier transform infrared spectroscopy) were used to reveal the binding of DOM with TC.
