Mechanisms and adsorption capacities of biochar for the removal of organic and inorganic pollutants from industrial wastewater

International Journal of Environmental Science and Technology, Journal Year: 2020, Volume and Issue: 18(10), P. 3273 - 3294

Published: Dec. 26, 2020

Abstract Currently, due to the rapid growth of urbanization and industrialization in developing countries, a large volume wastewater is produced from industries that contain chemicals generating high environmental risks affecting human health economy if not treated properly. Consequently, development sustainable low-cost treatment approach has attracted more attention policymakers scientists. The present review highlights recent applications biochar removing organic inorganic pollutants industrial effluents. modes preparation, physicochemical properties adsorption mechanisms are also reviewed comprehensively. Biochar showed dyes up 80%. It discusses application mechanism biochar-supported photocatalytic materials for degradation contaminants wastewater. We possible optimizations (such as pyrolysis temperature, solution pH) allowing increase capabilities leading removal. Besides, increasing temperature was seen lead an its surface area, while it decreases their amount oxygen-containing functional groups, consequently decrease metal (loid) ions medium. Finally, suggests research should be carried out optimize main parameters involved production regeneration methods. Future efforts towards process engineering improve capacity economic benefits implementation.

Multifunctional applications of biochar beyond carbon storage

International Materials Reviews, Journal Year: 2021, Volume and Issue: 67(2), P. 150 - 200

Published: May 7, 2021

Biochar is produced as a charred material with high surface area and abundant functional groups by pyrolysis, which refers to the process of thermochemical decomposition organic at elevated temperatures in absence oxygen. The carbon component biochar relatively stable, and, hence, was originally proposed soil amendment store soil. has multifunctional values that include use it for following purposes: improve health, nutrient microbial carrier, immobilising agent remediation toxic metals contaminants water, catalyst industrial applications, porous mitigating greenhouse gas emissions odorous compounds, feed supplement animal health intake efficiency thus, productivity. This article provides first time an overview unintended consequences applications.

Heavy metal pollution in the aquatic environment: efficient and low-cost removal approaches to eliminate their toxicity: a review

RSC Advances, Journal Year: 2023, Volume and Issue: 13(26), P. 17595 - 17610

Published: Jan. 1, 2023

Heavy metal contamination of water sources has emerged as a major global environmental concern, threatening both aquatic ecosystems and human health. pollution in the environment is on rise due to industrialization, climate change, urbanization. Sources include mining waste, landfill leachates, municipal industrial wastewater, urban runoff, natural phenomena such volcanic eruptions, weathering, rock abrasion. ions are toxic, potentially carcinogenic, can bioaccumulate biological systems. metals cause harm various organs, including neurological system, liver, lungs, kidneys, stomach, skin, reproductive systems, even at low exposure levels. Efforts find efficient methods remove heavy from wastewater have increased recent years. Although some approaches effectively contaminants, their high preparation usage costs may limit practical applications. Many review articles been published toxicity treatment for removing wastewater. This focuses main pollution, chemical transformation, toxicological impacts environment, harmful effects ecosystem. It also examines advances cost-effective techniques physicochemical adsorption using biochar zeolite ion exchangers, well decomposition complexes through advanced oxidation processes (AOPs). Finally, advantages, applications, future potential these discussed, along with any challenges limitations that must be considered.
