Biochar for the removal of contaminants from soil and water: a review

Biochar, Journal Year: 2022, Volume and Issue: 4(1)

Published: March 15, 2022

Abstract Biochar shows significant potential to serve as a globally applicable material remediate water and soil owing the extensive availability of feedstocks conducive physio-chemical surface characteristics. This review aims highlight biochar production technologies, characteristics biochar, latest advancements in immobilizing eliminating heavy metal ions organic pollutants water. Pyrolysis temperature, heat transfer rate, residence time, type feedstock are critical influential parameters. Biochar’s efficacy managing contaminants relies on pore size distribution, groups, ion-exchange capacity. The molecular composition physical architecture may be crucial when practically applied soil. In general, produced at relatively high pyrolysis temperatures can effectively manage via increasing area, hydrophobicity microporosity. generated lower is deemed more suitable for removing polar inorganic through oxygen-containing functional precipitation electrostatic attraction. also presents existing obstacles future research direction related biochar-based materials effluents Graphical

Sustainable adsorptive removal of antibiotic residues by chitosan composites: An insight into current developments and future recommendations

Arabian Journal of Chemistry, Journal Year: 2022, Volume and Issue: 15(5), P. 103743 - 103743

Published: Jan. 29, 2022

During COVID-19 crisis, water pollution caused by pharmaceutical residuals have enormously aggravated since millions of patients worldwide are consuming tons drugs daily. Antibiotics the preponderance pollutants in bodies that surely cause a real threat to human life and ecosystems. The excellent characteristics chitosan such as nontoxicity, easy functionality, biodegradability, availability nature abundant hydroxyl amine groups onto its backbone make it promising adsorbent. Herein, we aimed provide comprehensive overview recent published research papers regarding removal antibiotics composite-based adsorbents. structure, ionic form, optimum pH λmax most common including Tetracycline, Ciprofloxacin, Amoxicillin, Levofloxacin, Ceftriaxone, Erythromycin, Norfloxacin, Ofloxacin, Doxycycline, Cefotaxime Sulfamethoxazole were summarized. development adsorbents order enhance their adsorption capacity, reusability validity presented. Moreover, mechanisms these explored more information about adsorbate-adsorbent interactions. Besides dominant factors on process pH, dosage, coexisting ions, etc. discussed. conclusions future recommendations provided inspire for further researches.

A Review on Application of Biochar in the Removal of Pharmaceutical Pollutants through Adsorption and Persulfate-Based AOPs

Sustainability, Journal Year: 2022, Volume and Issue: 14(16), P. 10128 - 10128

Published: Aug. 16, 2022

Increasing quantities of pharmaceutical pollutants have been found in aquatic ecosystems. The treatment has a major task that people committed to recent years. removal can be achieved by adsorption and advanced oxidation processes (AOPs). Compared with other carbon materials, biochar strong capacity persulfate activation ability, more importantly, is cheap easy obtain; thus, it higher economic benefits. This study firstly reviews the application drugs (tetracycline (TC), sulfamethoxazole (SMX), acetaminophen (ACT), cephalexin (CPX), levofloxacin (LEV), etc.) through persulfate-based AOPs. In addition, we summarize mechanism for various main attack sites on different AOPs catalyzed biochar. Finally, challenges prospects respect are put forward.
