Abstract The presence of antibiotics in the environment has raised concerns due to their potential negative effects on ecosystems. Conventional water treatment methods are ineffective at removing antibiotics. This study aims investigate efficiency Fenton-like processes catalyzed by delaminated clay and layered double hydroxides impregnated with Fe or Cu for degradation amoxicillin. catalysts were obtained synthesizing subsequently impregnating them Cu. characterization involved X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence (XRF), N2 adsorption-desorption, photoelectron spectroscopy (XPS). Catalytic activity was assessed varying concentration hydrogen peroxide, initial amoxicillin, amount catalyst. determination byproducts done high-performance liquid chromatography (HPLC) a quadrupole time-of-flight mass spectrometer (QqTof). found that able remove 100% amoxicillin just 20 min. identified 16 byproducts, indicating process. Under all studied conditions, copper showed highest percentage removal.

Abstract In this study, the mesoporous material NCNT was prepared by treating carbon nanotubes (CNT) with hydrazine and subsequently loaded Cu-Fe layered double hydroxide (CuFeLDH) to create a multiphase catalyst (CuFeLDH-NCNT). Its application as investigated in an ultrasound-assisted Fenton process for ciprofloxacin (CIP) degradation aqueous solution. addition, impacts of dosage, ultrasonic power, H2O2 beginning pH on CIP removal efficiency were carefully evaluated maximize CIP. The findings indicated that elimination rate initial concentration 20 mg/L surpassed 94.66% after mere 100 min, while TOC 70.4%. high due synergistic action between nanoparticles, H2O2, ultrasonography. intermediates examined, putative pathways mechanisms postulated.

Disodium octoborate tetrahydrate (DOT) is a well-received and eco-friendly preservative. However, it prone to leaching from wood in humid conditions or rainy seasons, causing problems such as decreased efficiency resisting fungi poor surface performance finishing. To obtain enhanced resistance simultaneously achieve controlled release of DOT, pH temperature dual responsive poly (2-hydroxyethyl methacrylate/2-(Dimethylamino) ethyl methacrylate) (PDH) was prepared optimized for situ construction DOT-loaded PDH (PDHD) wood. Results showed that displayed obvious temperature-responsive swelling, when loaded with the PDHD consequently released DOT way. Fourier transform infrared spectroscopy, Solid-13C NMR analysis Dynamic mechanical confirmed copolymerization 2-Hydroxyethyl methacrylate (HEMA) 2-(Dimethylamino) (DMAEMA), well presence crosslinked structure formed hydrogen bond between hydroxyl group HEMA N,N-dimethylamino groups DMAEMA. After that, constructed boron. During water test, modified exhibited boron fixation rate 49.05% compared 0.72% neat DOT-treated Besides, presented activity response temperature. This work provides new approaches preservatives notably realizes releasing compounds long-term preservation.
