Removed heavy metal ions from wastewater reuse for chemiluminescence: Successive application of lignin-based composite hydrogels

Gao-Jie Jiao et al.

Summary: The novel sulfomethylated lignin-grafted-polyacrylic acid (SL-g-PAA) hydrogel was fabricated for efficient removal of heavy metal ions from wastewater, and successfully reused for chemiluminescence. The hydrogel showed high content of lignin and exhibited efficient removal of various metal ions, while the spent hydrogel was reused to develop a new CL system with high intensity and long duration time. The combination of facile fabrication process, renewable raw materials, and ingenious strategy for successive application in adsorption and CL suggest great potential for application in wastewater treatment, biological imaging, and cold light sources.

Anushka Upamali Rajapaksha et al.

Summary: This systematic review discusses the performance and applicability of several adsorptive materials for the removal of hexavalent chromium (Cr(VI)) from water, as well as the mechanisms involved. Statistical analysis is used to compare the effectiveness of different adsorbents and the effects of sorbent properties and experimental conditions. The factors involved in fixed-bed column studies are also analyzed. The study also examines the regeneration of spent adsorbent and its reuse. Nanoparticles and mineral-doped biochar are found to be the most effective sorbents.

Mechanism of Removal of Hexavalent Chromium from Aqueous Solution by Fe-Modified Biochar and Its Application

Run Pan et al.

Summary: This study investigated the mechanism of Fe-modified biochar (FeBC) derived from rice straw biochar (BC) as an adsorbent for removing Cr(VI) from aqueous solution. The results showed that the removal percentage of Cr(VI) increased with the FeBC dose, and increasing solution pH slightly decreased Cr(VI) adsorption. Coexisting ions such as Ca2+, Na+, and Cl- inhibited the removal of Cr(VI). Analytical techniques revealed that FeBC had more active sites with loaded iron oxides compared to BC, and the surface functional groups changed. The removal of Cr(VI) by FeBC was mainly attributed to electrostatic adsorption and the redox reaction of Cr and Fe. FeBC exhibited good removal performance on actual industrial wastewater.

Effect of the porosity and microstructure on the mechanical properties of organic xerogels

S. L. Flores-Lopez et al.

Summary: The synthesis of resorcinol-formaldehyde (RF) xerogels allows for customization of pore size distributions in the meso-/macroporous range. Compression tests revealed a power-law relationship between mechanical properties and density, with two series of RF xerogels showing unexpectedly high compression moduli at the more acidic pH values. The microstructure of the xerogels includes rod-like structures that bear loads during compression tests, leading to catastrophic failure upon breaking.

Under pressure: Hydrogel swelling in a granular medium

Jean-Francois Louf et al.

Summary: Hydrogels show promise in agriculture as water reservoirs in dry soil, but their ability to swell can be reduced when confined in soil due to competition between osmotic swelling force and confining force. The medium can also be restructured by hydrogel swelling, depending on the balance of forces involved. These findings offer quantitative principles to predict hydrogel behavior in confinement, potentially improving their agricultural use and informing other applications.
