AI Article Synopsis
- Researchers improved wastewater treatment by modifying magnetic fly ash particles with polymer groups to create a composite microgel for adsorbing lead ions.
- They used an easy process called inverse suspension polymerization without extra organic crosslinkers.
- The resulting magnetic microgels showed increased stability and allowed for easier separation from wastewater.
Article Abstract
In order to improve the performance of treating waste-water with wastes, the magnetic fly ash (FA) particles were surface-modified with polymerizable groups as the crosslinker for the copolymerization with acrylic acid (AA) and acrylamide (AM) by a facile inverse suspension polymerization process, without any foreign organic crosslinker added. The optimized beadlike magnetic fly ash/poly(acrylic acid-co-acrylamide) composite microgels (FA/P(AA-AM)) with 3-dimensional crosslinking skeleton structure were selected as the magnetic selective microgel adsorbent for Pb(2+) ion, through a series of L(9)(3(4)) orthogonal experiments. It was found that the magnetic FA particles could improve the strength stability of the FA/P(AA-AM) composite microgels, also provide the ability of magnetic separation.

Microgels are versatile materials with applications across biomedicine, materials science, and beyond. Their controllable size and composition enables tailoring specific properties, yet characterizing their internal structures on the nanoscale remains challenging. Super-resolution fluorescence microscopy (SRFM) effectively analyzes sub-μm structures, including microgels, offering a tool for investigating more complex systems such as core-shell microgels.

This work investigated the effects of curdlan gum-guar gum composite microgels (CG microgels) as a fat replacer on the gel properties, water distribution, and microstructures of pork meat batters, using techniques including rheometry, SEM, and LF-NMR. Between 55 °C and 80 °C, the addition of 30 % CG microgels enhanced the viscoelastic response of pork meat batters. Additionally, the CG microgels reduced cooking loss from 18.

Hierarchical porous composite microgels (SPZ microgels) were synthesized using microfluidic technology, composed of sodium alginate (SA), polyvinyl alcohol (PVA), and zeolitic imidazolate framework-8 (ZIF-8). The incorporation of ZIF-8 nanoparticles led to the formation of significant porous structures within the microgels, greatly enhancing their dye adsorption performance. Additionally, the diffusion of acetone during the crosslinking reaction resulted in sodium chloride crystal formation, creating a hierarchical porous structure with larger internal porous channels and smaller external channels.
