A Comprehensive Review of the Application and Potential of Straw Biochar in the Remediation of Heavy Metal-Contaminated Soil

Toxics, Год журнала: 2025, Номер 13(2), С. 69 - 69

Опубликована: Янв. 21, 2025

With the rapid development of industry and agriculture, soil heavy metal contamination has become an important environmental issue faced today gradually attracted widespread attention. Finding a cheap, widely available, biodegradable material that can promote crop growth stabilize metals research focus. Crop straw biochar, due to its high specific surface area, rich functional groups, cation exchange capacity (CEC), shown good effects on remediation inorganic organic pollutants in environment. This article reviews recent use biochar for remediation, providing detailed analysis from preparation, characteristics, modification mechanisms reducing toxicity soil, application risks remediating metal-contaminated soils. It also comprehensively discusses potential The results show be used as new type immobilizing soils, but there are issues with technology needs optimized innovated, which poses challenges biochar. In future, efforts should strengthened optimize innovate conduct cheap modified co-application other materials carry out long-term monitoring order achieve goal ensuring food safety rational solid waste.

Synthesis of nitrogen-purged biochar and modification with hydrothermal activation: comparative assessment as adsorbents for effective elimination of Pb(II) and Cd(II) from wastewater

Deleted Journal, Год журнала: 2025, Номер 7(2)

For sustainable development, wastewater treatment and recycling are inevitable; using adsorbents to treat is widely accepted. This article aimed synthesize (novel biochars) from agricultural wastes investigate the adsorption behaviours of Pb(II) Cd(II) on novel biochars. Nitrogen purged biochar (NPBC) was synthesized by pyrolysis with nitrogen purgation wheat straw; whereas, steam activated (SABC) pyrolysis-cum-hydrothermal (steam) activation. Synthesized NPBC SABC were characterized physical, chemical, XRD, FTIR, SEM–EDX methods. more porous amorphous in nature higher specific surface area (SSA), but consisted relatively less polar functional groups than that NPBC. The external layer both negatively charged (pH > pHPZC). Results revealed exhibited 97% 80% recovery efficiency Cd(II), respectively, while demonstrated removal efficiencies 87.6% 69.4%, at initial concentrations 50 5 mg L−1. Adsorption upon occurred spontaneously, also exothermically, decreased increased reaction temperature. maximum capacities (qmax) for 452.13 1117 g−1, whereas those 314.9 470.43 according Langmuir isotherm approach (R2 0.989). So, performed better removing metals wastewater. Both exhibit substantial prospects regeneration consequent adsorbent recovery. Hence, designed can be very effective towards cationic toxic heavy metal

The discharge of lead and cadmium wastewater, along with the pollution caused by phosphogypsum, represents a particularly urgent environmental issue. This study employed straightforward hydrothermal method to convert phosphogypsum into porous calcium silicate hydrate (P-CSH), which was then used remove recover Pb(II) Cd(II) from wastewater. adsorption capacities P-CSH for were notably high at 989.3 mg/g 290.3 mg/g, respectively. processes adhered pseudo-second-order kinetics model Langmuir isotherm model. Due identical sites on both Cd(II), competitive interaction occurred when ions present simultaneously. Additionally, efficacy minimally impacted presence common coexisting cations in dominant mechanisms removing via chemical precipitation surface complexation. Moreover, adsorbed heavy metals efficiently separated reclaimed wastewater through stepwise desorption process. primary components residue quartz amorphous SiO2. Following dissolution pressurized alkaline leaching, this could be recycled synthesizing P-CSH. research offered new strategy resourceful use metal
