Abstract Green-based materials represent a new promising class of ecofriendly and economic adsorbents. Herein, nano zero-valent iron supported-lemon derived biochar (NZVI-LBC) was prepared for the first time examined in adsorptive removal methylene blue as model pollutant. Different characterization tools were used to ensure successful fabrication NZVI-LBC composite including FTIR, XRD, TEM, XPS, VSM, BET, zeta potential analysis. It found that fabricated NZVI–supported attained propitious adsorbent criteria since it provided supreme efficient adsorption process at short time. The reckoned maximum capacity MB onto reached 1959.94 mg/g within merely 5 min. obtained data clarified fitted pseudo 2 nd order kinetic Freundlich isotherm model. Besides, be endothermic nature. In addition, revealed an excellent behavior even after seven cycles. concrete results reflect potentiality superb candidate remove cationic pollutants from their aqueous solutions.

Nanobiochar for the remediation of contaminated soil and water: challenges and opportunities

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: Jan. 13, 2023

Abstract Although research on biochar has received increasing attention for environmental and agricultural applications, the significance of nanobiochar pollutant remediation is poorly understood. In contrast to bulk biochar, superior physicochemical properties such as high catalytic activity, unique nanostructure, large specific surface area mobility in soil environment. These characteristics make an ideal candidate pollution remediation. Thus far, still its infancy most previous studies have only been conducted exploring functions. The lack in-depth summary nanobiochar’s direction makes it a challenge scientists researchers globally. Hence this review, we established some key fabrication methods with focus performance removal pollutants from We also provided up-to-date information role insights into different mechanisms involved removal. Although, application increasing, associated drawbacks ecosystem not enough attention. Therefore, further warranted evaluate potential risks before scale application. Graphical

Removal of pharmaceuticals from wastewater: A review of adsorptive approaches, modelling and mechanisms for metformin and macrolides

Journal of environmental chemical engineering, Journal Year: 2022, Volume and Issue: 10(4), P. 108106 - 108106

The usage of pharmaceuticals (PhCs) as an integral part human healthcare is growing globally. However, most current wastewater treatment plants (WWTPs) are not designed for the removal PhC residues, effective and cost-efficient new technologies required to meet this challenge. Adsorption has proven be efficient method, however, traditional adsorbents e.g., activated carbons ion-exchange resins often excessively costly. Therefore, there a interest in novel low-cost adsorbents, which have high affinity toward PhCs. This review focussed on two priority pharmaceutical classes, metformin (MF) biguanide, macrolides (e.g., clarithromycin, erythromycin, azithromycin) assesses isotherm, kinetic thermodynamic studies (and modelling), well adsorption mechanisms with discussion some identified mistakes inconsistencies. also sought identify gaps knowledge that should priorities future investigations. indicated maximum capacities from Langmuir isotherm were found 0.34–278 mg/g MF 7.56–340 macrolides. Data showed kinetics represented by pseudo-second order model mass transfer was predominantly controlled both film intraparticle diffusion. little information literature involved these compounds, or involving dynamic conditions real-world application (real effluents environmentally relevant concentrations). include scale-up, effluent studies, cost-analysis environmental impact Life Cycle Analysis).
