Heavy metal pollution is posing significant threats to the environment and human health. Engineered biochar, derived from various biomass sources through thermochemical processes, has emerged as a promising solution for pollutant remediation recovery. This review explores latest advancements in preparation, characterization, application of engineered biochar adsorption, recycling, utilization. It begins by discussing significance adsorption providing an overview properties. The examines preparation characterization techniques, emphasizing feedstock selection, conversion methods, surface modifications. Mechanisms such physical chemical ion exchange, complexation, are critically discussed. Moreover, factors influencing capacity, including properties, characteristics, environmental conditions, analyzed. efficacy adsorbing specific metals, heavy transition rare earth elements, reviewed with recent studies key findings. Furthermore, recycling regeneration metal-loaded discussed, focusing on repurposed techniques alongside challenges economic considerations. Finally, future perspectives provided enlightening research. unique addressing potential metal-adsorbed novel precursor produce catalytical electrochemical materials.

Due to their remarkable adsorptive qualities, low cost, and wide availability, iron oxides hydroxides have attracted a lot of interest as efficient materials for the removal heavy metals from wastewater. The mechanisms by which iron-based minerals, such ferrihydrite, magnetite, haematite goethite interact with through ion exchange, co-precipitation, adsorption are covered in detail this chapter. In order maximise metal uptake efficiency, importance surface chemistry, particle size mineral crystallinity is emphasised. This study critically examines developments oxide functionalisation modification improve capacity selectivity particular metals, including cadmium, lead arsenic. While there naturally occurring oxides/hydroxides, it possible synthesise them, coupling synthesis modifications, these usually monitored or verified using easily accessible instruments X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) Fourier Transform Infrared Spectroscopy (FTIR). integration oxides/hydroxides nanotechnology polymers has been beneficial both other pollutants, organic ones, highlights versatility materials. ability be regenerated further use makes them attractive wastewater treatment industry terms environmental beneficiation. chapter, therefore, provides comprehensive analysis hydroxides, highlighting crucial role developing sustainable systems reducing pollution.

Abstract Heavy metal contaminated soil remediation methods are mostly chemical washing, fixed stabilization, and bioremediation techniques. However, drenching can cause secondary pollution; fixation stabilization is incomplete may fail; has a long time period. Therefore, in this study, we synthesized stable millimeter‐scale gel spherical adsorbent, UIO‐66‐NH 2 @SA, to remove the pollutants from with high concentrations of heavy metals by combination aqueous leaching adsorption without addition additional agents. The @SA be recovered sieving, it still capacity removing after four adsorption–desorption cycles. analysis properties before proved that process would not affect physicochemical fertility soil, characterization x‐ray diffraction, Fourier transform infrared, XPS mechanism was mainly ion exchange functional group complexation.
