“…The biochar created at a low temperature (350 °C) revealed smaller surface area (0.25 m 2 /g), higher H/C (0.905) and K (1.94%) content, as well as the maximum elimination capacity (161 mg/g). Biochar obtained from sugarcane in the agro-industry by low-temperature pyrolysis exhibited approximately 70% removal efficiency of thiamethoxam in 60 min (Fernandes et al 2021). In addition, biochar synthesized from phosphoric acid-treated rice straw (T-RSBC) was used for the removal of atrazine (ATZ), azoxystrobin (AZOXY), and imidacloprid (IMIDA) in single-, bi-, and ternary-solute systems (Mandal et al 2021).…”

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

“…Ionic pesticides mainly react with soil particles through ion exchange and hydrogen bonding, while organic pesticides that are easily dissociated into cations can be adsorbed in soil or sediments through cation exchange (ionic bonding). e literature [6] found that the content of organic matter in the soil plays a decisive role in the adsorption of nonionic herbicides to a certain extent. However, mineral components have little effect on its adsorption, while ionic herbicides have the opposite effect.…”

In this paper, research on pesticide adsorption mechanism of corn straw biochar based on KOH thermal activation is carried out. In this paper, corn stalks and pine needles are used as raw materials for preparing biomass charcoal, and biochar is prepared at temperatures of 200°C, 400°C, and 600°C. This paper uses thermogravimetric analysis, elemental analysis, electron microscopy scanning, aperture measurement, infrared spectroscopy, and other characterization techniques to analyze the structure and properties of biochar in detail. Moreover, this paper uses batch method to select different organic pesticides diuron and carbaryl to test their adsorption performance. This article discusses the relationship between the adsorption mechanism and structural characteristics of biochar for organic pollutants. In addition, this paper studies the adsorption mechanism of diuron and carbaryl in the loess by adding exogenous biochar to the loess. Finally, this article analyzes the impact of the addition of biochar on the environmental behavior of diesel-contaminated loess adsorption of organic pollutants. This paper studies the role of KOH thermally activated corn stover biochar in agricultural adsorption, and verifies the reliability of the method proposed in this paper through experimental studies.

“…Brazil is one of the world's largest producers of food, fiber, and energy materials (CONAB 2021;FAOSTAT 2019). Thus, there is large availability of biomass for biochar production, which has potential to be used in various areas of interest (e.g., agriculture, environmental sciences, engineering, biotechnology) (Lefebvre et al, 2020;Novotny et al, 2015;Torres et al, 2021).…”

Biochar has been intensively researched worldwide. In Brazil, there is a variety of feedstock production that can be turned into soil amendments of high performance through biochar conversion, especially solid wastes. However, advances in biochar research in Brazil have not been systematically evaluated to indicate possible gaps and suggest future research for eco-friendly applications. Thus, in this work we evaluated biochar properties and effects on air, water, and soil quality based on data gathered from researches performed in Brazil. Biochar has been mainly evaluated as soil conditioner (37%), material characterization (17%), water treatment (12%), and greenhouse gases emissions (9%). Based on the data synthesis of 68 feedstocks used for biochar production, we observed that the pyrolysis temperature profoundly affects biochar properties. Meta-analysis indicated benefits of biochar addition to soils for chemical, physical, microbiological and biochemical attributes that have resulted in increases in root growth (+30%), and plant shoots (+45%). Pyrolysis temperature and feedstock are key choices to design biochar properties aiming to retain dyes, aromatic hydrocarbon, pesticides, and metals in water and wastewater treatment. It was also observed an increase in CO 2 and a decrease in N 2 O emissions after biochar application to soils in short-term experiments. Although there is a growing interest in the development of electrochemical sensors and biochar-based fertilizers, technological applications of biochar are still incipient in Brazil. Future research should prioritize long-term and mechanistically evaluations of biochar under field conditions and the development of eco-friendly technological applications.
