Advanced adsorbents for ibuprofen removal from aquatic environments: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 22(1), P. 373 - 418

Published: Aug. 25, 2023

Abstract The presence of pharmaceuticals in ecosystems is a major health issue, calling for advanced methods to clean wastewater before effluents reach rivers. Here, we review adsorption remove ibuprofen, with focus on ibuprofen occurrence and toxicity, adsorbents, kinetics, isotherms. Adsorbents include carbon- silica-based materials, metal–organic frameworks, clays, polymers, bioadsorbents. Carbon-based adsorbents allow the highest from 10.8 408 mg/g activated carbon 2.5–1033 biochar. Metal–organic frameworks appear promising due their high surface areas tunable properties morphology. 95% published reports reveal that kinetics follow pseudo-second-order model, indicating predominantly governed by chemical adsorption. 70% disclose Langmuir model describes isotherm, suggesting involves monolayer

The removal of antibiotics in water receiving bodies is an integral part eradicating antimicrobial resistance which has become a major threat to public health. Solid-liquid adsorption demonstrated be effective technique the from aqueous environments. Herein, chitosan-carbon nanotube (chitosan-CNT) hydrogel beads were synthesised for amoxicillin (AMX), ciprofloxacin (CIP) and sulfamethoxazole (SMX) solution. Adsorption kinetics, isotherms thermodynamic parameters systematically investigated at solution pH 7. Single kinetics findings suggest that experimental data AMX, CIP SMX was better fitted by nonlinear pseudo-first order model with calculated maximum capacities 23.1 mg.g−1, 23.7 mg.g−1 25.17 respectively. Moreover, Weber-Morris kinetic multiple processes limiting overall rate on chitosan-CNT. isotherm results indicated single Freundlich model, while binary ternary system competitive extended Sips models. showed multicomponent systems exhibited both antagonistic synergistic SMX. From thermodynamics fundings, it evident endothermic process governed physical chemical mechanisms. Based current study, concluded chitosan-CNT potential as green technology

Removal of Cr(VI) from aqueous solution using ball mill modified biochar: multivariate modeling, optimization and experimental study

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Feb. 28, 2024

Abstract Chromium (Cr(VI)) pollution has attracted wide attention due to its high toxicity and carcinogenicity. Modified biochar been widely used in the removal of Cr(VI) water as an efficient green adsorbent. However, existing prepared by chemical modification is usually complicated process, cost, secondary pollution, which limits application. It urgent explore modified with simple low cost environmental friendliness. Therefore, ball milling wheat straw (BM-WB) was technology this paper. The adsorption characteristics mechanism BM-WB were analyzed functional group characterization, model response surface method. results showed that effectively reduced particle size biochar, increased specific area, more importantly, enhanced content oxygen-containing groups on biochar. After milling, capacity 3.5–9.1 times, reached 52.21 mg/g. behavior follows pseudo-second-order kinetics Langmuir isotherm rate. Moreover, process endothermic spontaneous. Under optimized conditions pH 2, temperature 45 °C, adsorbent dosage 0.1 g, rate solution can reach 100%. mainly based electrostatic attraction, redox complexation. milled a cheap, material, good application prospect field remediation water.
