A comprehensive review on the chemical regeneration of biochar adsorbent for sustainable wastewater treatment

npj Clean Water, Journal Year: 2022, Volume and Issue: 5(1)

Published: July 11, 2022

Abstract The chemical regeneration process has been extensively applied to reactivate biochar, supporting its reusability and leading significant operating cost reduction. However, no recent review discusses the effectiveness of biochar regeneration. Thus, this article comprehensively reviews contaminated with organic inorganic pollutants. Performance depends on adsorption mechanism, functional groups, adsorbent pore structure, changes in active sites. Secondary contamination is one challenges facing sustainable adaptation industry. paper these draws a roadmap for future research support wastewater treatment by biochar.

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.

Surface Modification of Biochar for Dye Removal from Wastewater

Catalysts, Journal Year: 2022, Volume and Issue: 12(8), P. 817 - 817

Published: July 26, 2022

Nowadays, biochar is being studied to a great degree because of its potential for carbon sequestration, soil improvement, climate change mitigation, catalysis, wastewater treatment, energy storage, and waste management. The present review emphasizes on the utilization biochar-based nanocomposites play key role in decontaminating dyes from wastewater. Numerous trials are underway synthesize functionalized, surface engineered that can sufficiently remove dye-contaminated removal via natural modified follows numerous mechanisms such as precipitation, complexation, ion exchange, cation–π interactions, electrostatic attraction. Further, production modification promote good adsorption capacity dye owing properties tailored stage linked with specific hydrophobic interactions. Meanwhile, framework artificial neural networking machine learning model efficiency proposed even though studies still their infancy stage. article recommends smart technologies modelling forecasting should be included proper applications.

Biochar application for remediation of organic toxic pollutants in contaminated soils; An update

Ecotoxicology and Environmental Safety, Journal Year: 2022, Volume and Issue: 248, P. 114322 - 114322

Published: Nov. 29, 2022

Bioremediation of organic contaminants has become a major environmental concern in the last few years, due to its bio-resistance and potential accumulate environment. The use diverse technologies, involving chemical physical principles, passive uptake utilizing sorption using ecofriendly substrates have drawn lot interest. Biochar got attention mainly simplicity manufacturing, treatment, disposal, as it is less expensive more efficient material, for remediation contaminants. This review highlighted adverse impact persistent pollutants on environment soil biota. utilization biochar remediate contaminated compounds i.e., pesticides, polycyclic aromatic hydrocarbons, antibiotics, dyes also been discussed. application significant biodegradation, leaching, sorption/desorption influenced by composition structure, porosity, surface area, pH, elemental ratios, functional groups biochar. All above characteristics depend type feedstock pyrolysis conditions. However, concentration nature significantly alters capability Therefore, physicochemical properties soils/wastewater, contaminants, should be evaluated before wastewater. Future initiatives, however, are needed develop biochars with better adsorption capacity, long-term sustainability xenobiotic/organic contaminant strategy.
