Heavy metal pollution is a serious environmental problem that poses threat to human health and the environment. Water by toxic heavy metals major cause of this problem, it can destroy ecosystems, spread disease, make drinking water unsafe. Biochar promising green adsorbent for removing from water. It derived various biomasses, including agricultural organic wastes, has high carbon content, surface area, stability. These properties enable biochar effectively remove through cation exchange adsorption. This review summarizes recent advances in modification enhanced adsorption metals. discusses advantages, applications, challenges, prospects method. Biochar-based advanced oxidation processes (AOPs) have shown promise decomposition complexes enhancement capacity free ions industrial wastewater. The also highlights research gaps limitations remediation proposes future directions. Future should focus on developing environmentally friendly cost-effective technologies scaling up biochar-based removal applications. Scheme 1 illustrates overall summarized presentation article as graphical abstract.

The multifunctional properties of biochar make it a promising adsorbent heavy metals for environmental bioremediation. Pyrolytic temperature is key factor that impacts the properties, performance, and mechanisms agro-wastes-derived because physiochemical transformation its structural composition. It has been deliberated increased pyrolysis temperatures strongly enhance specific surface area, pH, high microporosity as well carbon ash content with low cation exchange capacity volatiles content. reason different from related to variations in lignin-cellulose structures moistures agro-waste biomasses. Biochar considered low-cost material shown convenient applicability rural areas developing countries where contamination emerging. A wide range pyrolytic distinctive characteristics biomass their capacities remove metals. Higher can exhibit higher areas, enhanced functional groups, stability than modified biochar. Different exhibited diverse adsorption on such rice husk corncob, efficiency increases selective hexavalent chromium [Cr(VI)], cadmium [Cd(II)] zinc [Zn(II)]. This review aimed understand pristine bioremediation biomasses obtained decision making process production costs. authors propose future investigations metal immobilization unlock full potential

Sludge-based biochar adsorbent: pore tuning mechanisms, challenges, and role in carbon sequestration

Biochar, Год журнала: 2023, Номер 5(1)

Опубликована: Дек. 7, 2023

Abstract Sludge biochar, a carbonized product of raw sludge, contains porous architectures that can act as epicenters for adsorbing external molecules through physical or chemical bonding. biochar also immobilizes innate micropollutants, which is advantageous over conventional sludge disposal methods. To date, numerous strategies have been discovered to improve morphology, but the influential factors, pore tuning mechanisms, and process feasibility remain imprecise. This knowledge gap limits our ability design robust sludge-based biochar. Herein, we present state-of-the-art synthesis methods with insight into structural transformation mechanisms. Roadblocks novel concepts improving architecture are highlighted. For first time, properties, adsorption performances, techno-economic perspectives were compared commercial activated carbon (AC) reveal precise challenges in application. More importantly, role sequestration detailed demonstrate environmental significance this technology. Eventually, review concludes an overview prospects outlook developing biochar-based research.
