“…What is worse, the long-term exposure to TCs induces chronic and even acute disease, endangering humans and the ecosystem [6]. To overcome the harmful impacts of TCs in water, various strategies have been explored in previous works, including adsorption [7,8], advanced oxidation [9,10], biodegradation [11,12], electrocatalysis [13,14], photocatalysis [15,16], filtration [17], and flocculation [18]. Among these approaches, photocatalysis is the most promising route to eliminate TCs through the conversion of solar light to chemical and thermal energies.…”

The photo-induced peroxymonosulfate (photo-PMS) reaction is a promising route to eliminate antibiotics from waste water. To achieve excellent photo-PMS activity in Mg–Fe layered double hydroxides (LDHs) for tetracycline hydrochloride (TCH) degradation under simulative solar-light irradiation, Mg–Fe LDHs-loaded polyacrylonitrile (Mg–Fe/PAN) nanofibers were in-situ prepared via the hydrothermal route. For comparison to the photocatalysis and photo-PMS process, the Mg–Fe/PAN-assisted photo-PMS process exhibited a better elimination activity for TCH elimination. In addition, the photo-PMS activities of Mg–Fe/PAN composites were greatly affected by Mg–Fe LDHs content, TCH concentration, pH, and inorganic salts. Among these Mg–Fe/PAN composites, the optimal MgFe2/PAN with a Mg/Fe molar ratio of 1:2 and a nominal Mg–Fe LDHs content of 2.0 wt. % removed 81.31% TCH solution of 80 mg L−1 TCH within 120 min. This enhanced photo-PMS capacity of MgFe2/PAN was ascribed to the abundant active sites formed by functional groups and oxygen defects for efficient TCH species adsorption and photon capturing, and the tight interface between Mg–Fe LDHs nanoparticles and PAN nanofibers for the rapid separation and transfer of photoinduced e−/h+ pairs. SO4•− and •O2− radicals were vital for the MgFe2/PAN-assisted photo-PMS reaction.

“…Continuous photodegradation reactions result in the degradation of organic matter on the surface of clay minerals, generating new adsorption sites that promote the adsorption process. Comparing the structure and composition of humic before and after photodegradation and their adsorption changes with clay minerals helps to explore the differences in photodegradation of humic from different sources and the adsorption mechanisms of clay minerals and photodegradation products of humic 12 . This enhances the theoretical understanding of changes in humic substance photodegradation under the in uence of clay minerals and the adsorption of its products by clay minerals.…”

The study systematically analyzes the photodegradation processes of humic in the plateau lake Erhai Lake and their interactions with clay minerals. The experiments simulate photodegradation reactions under natural conditions, comparing the changes before and after photodegradation reactions. The reduction in total organic carbon (TOC) and changes in the functional groups of organic matter in the photodegradation products of humic are recorded. Aromatic and aliphatic compounds have a key role in humic photodegradation. The photodegradation rate of humic shows a nonlinear change, and The presence of clay minerals accelerates the photodegradation process of humic. The adsorption effects of clay minerals significantly alter the photochemical behavior of humic. Under the influence of clay minerals, the adsorption of humic by clay minerals increases their contact with photons, thereby enhancing the photodegradation efficiency of humic. The continuous photodegradation reaction continuously reduces the particle size of humic adsorbed on the surface of clay minerals, further increasing the adsorption of humic on the surface of clay minerals, accelerating the entire system.
