Enhanced nitrate reduction by HPMC-stabilized nanoscale zero-valent iron (H-NZVI): Synthesis, characterization and reaction kinetics

Desalination and Water Treatment
Nano zero-valent iron (NZVI) was successfully stabilized by using hydroxypropyl methyl cellulose (HPMC). Systematic characterization observations (including XRD, TEM, FTIR, and VSM), as well as settling performance, illustrated that, compared to bare ...

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

Modified Biochar for Wastewater Nutrient Recovery and Slow‐Release Fertilization in Sandy Agroecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Modified biochars are increasingly recognized as multifunctional materials for wastewater nutrient recovery and slow‐release fertilization in sandy agroecosystems. This review evaluates modified biochars, with particular emphasis on tyre‐derived biochar (TBC), for (i) recovery of nitrogen (N) and phosphorus (P) from wastewater and digestate ...
