To overcome the disadvantage of difficult recovery powder catalysts and improve catalyst utilization, selection foam metal substrates as supports can reduce difficulty material effectively inhibit leaching ions. Herein, CoMnNi-layered double hydroxide (LDH) derived from Co-Mn ZIF was immobilized onto nickel (NF) through in situ synthesis. The results XRD SEM analyses samples indicated that LDH successfully grown on matrix, could maintain its original morphology to maximum extent after loading. By comparing XPS before reaction, it confirmed surface hydroxyl group C=O were involved activation peroxymonosulfate (PMS). quenching reaction showed SO4•− 1O2 are main active substances oxidation enrofloxacin (ENR). When dosage NF@CoMnNi-LDH 0.4 g/L, pH solution 6.82, when PMS 2.0 mM, degradation rate ENR reached 82.6% within 30 min. This research offers novel insights into antibiotics water using a monolithic supported by foam.

A Gallic Acid–Acrylic Acid Graft Copolymer With High Oxygen Absorption Properties

Journal of Applied Polymer Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

ABSTRACT Gallic acid (GA), a potential deoxidizer utilized in food packaging, exhibits robust oxygen‐absorbing effect, yet suffers from poor stability. When integrated into polymers, its properties undergo significant decline. This research is focused on graft copolymerizing GA with acrylic (AA) to create water‐absorbing resin (GA‐PAA) that boasts high‐oxygen‐absorbing capabilities. minimizes loss during production and eliminates the need for an alkaline environment oxygen absorption. The single‐variable method being employed investigate impact of synthesis conditions GA‐PAA's performance. Initial findings indicate optimal performance mass ratios 7% GA, 0.6% initiator, 0.2% cross‐linking agent, along 80% degree neutralization reaction temperature 80°C. GA‐PAA characterized as highly absorbent both water, confirming successful grafting GA. Well‐synthesized resins exhibit water absorption capacity 452.2 g/g scavenging 105.3 mL/g before hydration. Posthydration, displays pattern initial sudden decrease, followed by gradual increase, dependent amount added. These suggest AA enhances GA's stability synthesis, enabling efficient oxygen‐scavenging materials.

The sustainability of aquaculture tailwater plays a key role in the industry. Photocatalytic degradation recalcitrant antibiotics has emerged as significant research focus, with gCN-based photocatalysis offering promising approach. To address issue inefficient associated gCN, melamine was modified using NaCl solution, resulting synthesis NaMe-x distinctive microstructure through molten salt assistance. ability to degrade tetracycline hydrochloride (TC-HCl) examined, including an analysis its pathway, intermediate products, mechanism, and toxicity by-products. results demonstrated that NaCl-based precursor modification markedly enhanced capacity gCN for TC-HCl, achieving maximum rate 0.02214 min−1, which is 2.1 times higher than unmodified gCN. LC-MS revealed intermediates at various stages, two potential pathways TC-HCl presence NaMe-1 were identified. In this process, ·O2− ·OH are reactive radicals play dominant role, their mechanism thus proposed. It confirmed by experiments products after not significantly toxic Chlorella vulgaris (p ˃ 0.05). However, it had effect on Vibrio fischeri < 0.01). These findings suggest via substantially improves performance enhances tailwater.
