Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1769-1795, April 2026.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

Study on iron anchoring methods for magnetic biochar: Characterization, functional mechanism, and RBBR dye removal

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1836-1851, April 2026.
Abstract Magnetic biochar (MBC) is a novel bio‐metallic composite material with high potential in sustainable water cleaning. Iron anchoring is critical in forming iron‐based MBC and will fundamentally impact its characteristics and functionality in dye removal applications. However, the mechanism is not well‐revealed.

Biogenic Synthesis of Silver and Iron Nanoparticles Derived From Grewia Optiva Leaf Extract: A Novel Approach for Antidiabetic, Anticoagulant and Anti‐Inflammatory Therapies

International Journal of Chemical Kinetics, Volume 58, Issue 4, Page 159-174, April 2026.
ABSTRACT This study presents the green synthesis of silver (Ag‐NPs) and iron nanoparticles (Fe‐NPs) using aqueous leaf extract of Grewia optiva as a natural reducing and stabilizing agent. The extract was prepared using a Kjeldahl apparatus under controlled heating. Nanoparticle synthesis was optimized by varying pH, temperature, and salt concentration,

Synthesis and characterisation of iron oxides: Effect of calcination temperature and their application as inorganic pigment

Coloration Technology, Volume 142, Issue 2, Page 222-235, April 2026.
Abstract This research aimed to investigate the effect of calcination temperature on the phase, morphological and optical properties of iron oxides: hematite (α‐Fe₂O₃), magnetite (Fe₃O₄) and goethite (α‐FeOOH), synthesised by co‐precipitation, aiming at their applications as pigments.

Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM2.5

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized. Here, we developed a robust methodology for the extraction, quantification, and source apportionment of magnetic NPs in urban PM2.5.
