Progress in agricultural waste derived biochar as adsorbents for wastewater treatment

Applied Surface Science Advances, Journal Year: 2023, Volume and Issue: 18, P. 100518 - 100518

Published: Dec. 1, 2023

The wastewater generated from diverse human activities needs to be treated, restore, and reused. Researchers have moved the deployment of synthetic absorbents manufacturing adsorbents waste biomass for elimination contaminants wastewater. biochar constructed agricultural has elicited significant devotion due its ready availability, accessibility, low cost, ease preparation, environmental sustainability. This review presents developments in utilization obtained remediation domestic wastewater, industrial stormwater. Discussions on classification, composition, characteristics waste, techniques production, as well outcomes decontamination were highlighted. study concludes that, notwithstanding identified environmental, social, economic, infrastructural challenges, is an effective, efficient, easy use, eco-friendly adsorbent Agricultural waste-derived removes safeguards aquatic ecosystem contributes availability safe water. Future research directions innovative more effective avenues application developed treatment are suggested. outcome this will stimulate renewed interests using readily available materials remediation.

The conversion of lignocellulosic agricultural waste into biofuels and other economically valuable compounds can reduce dependence on fossil fuels, harmful gas emissions, support the sustainability natural resources, including water, minimize amount in landfills, thus reducing environmental degradation. In this paper, wastes biomethane, biohydrogen, biodiesel, bioethanol, biobutanol, bio-oil is reviewed, with special emphasis primary secondary residues as substrates. Some novel approaches are mentioned that offer opportunities to increase efficiency valorization, e.g., hybrid systems. addition physical, chemical, biological pretreatment waste, some combined methods mitigate negative effects various recalcitrant processing (alkali-assisted thermal pretreatment, hydrolysis alkali bioaugmentation) evaluated. addition, production volatile fatty acids, polyhydroxyalkanoates, biochar, hydrochar, cellulosic nanomaterials, selected platform chemicals from described. Finally, potential uses recovered products discussed.

Evaluation of the Adsorptive Performances of Rapeseed Waste in the Removal of Toxic Metal Ions in Aqueous Media

Water, Journal Year: 2022, Volume and Issue: 14(24), P. 4108 - 4108

Rapeseed seeds are one of the most important categories raw materials used to obtain biofuels. However, biomass resulting after oil extraction is still considered waste, for which valorization solutions sought. In this study, we propose use type residual (rapeseed waste (RWB)) as a biosorbent removal toxic metal ions from aqueous media. Two were selected experimental studies, namely: Pb(II) and Hg(II). The optimal biosorption conditions, both ions, based on response surface methodology verified experimentally in batch systems. More than 92% initial amount Hg(II) retained under following conditions: pH = 6.5 4.0 Hg(II); dosage g/L; contact time 3 h; temperature 25 ± 1 °C. Isotherm (Langmuir, Freundlich Temkin models) kinetic (pseudo-first order, pseudo-second order intra-particle diffusion modelling data quantitative evaluation processes. Although Langmuir maximum capacities different (higher case (61.97 mg/g) (51.32 mg/g)), constants have same magnitude. This shows that retention involves similar elementary steps RWB behaves typical biosorbent. These characteristics, together with very good desorption behavior, provide complete picture possible applications environmental decontamination
