Removal of toxic elements from aqueous environments using nano zero-valent iron- and iron oxide-modified biochar: a review

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

Published: April 11, 2022

Abstract Biochar (BC) has gained attention for removal of toxic elements (TEs) from aqueous media; however, pristine biochar often exhibits low adsorption capability. Thus, various modification strategies in BC have been developed to improve its capability against TEs. Nanoscale zero-valent iron (nZVI) and oxides (FeOx) used as sorbents TE removal. However, these materials are prone agglomeration also expensive, which make their usage limited large-scale applications. The nZVI technical demerits could be resolved by the development BC-based composite through loading or FeOx onto surface. Nano modified (nZVIBC), FeOx-modified (FeOxBC) attracted removing pollutants phases. Nonetheless, a potential use nZVIBC FeOxBC environments not well-realized reviewed. As such, this article reviews: (i) preparation characterization FeOxBC; (ii) capacity retention line with physicochemical properties, (iii) mechanisms FeOxBC. Adopting increases sporptive TEs due surface modifications morphology, functional groups, elemental composition. combined effects nZVI, Fe salts on sorption complex because they very specific This review identified significant opportunities research technology advancement novel effective remediation contaminated water.

Abstract To decrease the eutrophication caused by nitrogen (N) and phosphorus (P) in water, magnesium-modified corn stalk biochar (MgB) was prepared under synergistic impact of multi-pyrolysis temperatures Mg 2+ contents for co-adsorption ammonium (NH 4 + -N) phosphate (PO 3− ). The mechanism, slow-release performance plant application MgB were systematically studied. results showed that pyrolysis (350–650 °C) (0–3.6 g/L) not only altered physicochemical properties biochar, but also significantly affected adsorption efficacy MgB. NH -N PO accordance with Langmuir–Freundlich pseudo-second-order kinetic models (Q max = 37.72 73.29 mg/g, respectively). Based on characteristics, kinetics isotherms results, mechanism determined found to mainly involve struvite precipitation, ion exchange, surface precipitation or electrostatic attraction. Compared leaching chemical fertilizers (CF), after (MgB-A), had a more stable pH lower conductivity. Leaching MgB-A controlled both diffusion dissolution rate Mg-P. excellent long-term abundant promoted growth Zea mays L. Lolium perenne Overall, this study suggested could realize win–win outcome biochar-based fertiliser production wastewater treatment.

A bibliographic study reviewing the last decade of hydrochar in environmental application: history, status quo, and trending research paths

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: March 13, 2023

Abstract Hydrothermal carbonization (HTC) technology has increasingly been considered for biomass conversion applications because of its economic and environmental advantages. As an HTC product, hydrochar widely used in the agricultural fields decades. A CiteSpace-based system analysis was conducting a bibliometric study to understand state application research from 2011 2021. Researchers had basic understanding between 2016 when they discovered could apply improvement projects. Keyword clustering results literature published 2017–2021 showed that soil quality plant growth were major topics, followed by carbon capture greenhouse gas emissions, organic pollutant removal, heavy metal adsorption bioavailability. This review also pointed out challenge perspective application, namely: (1) effects on soils need be clarified terms scope conditions; (2) influence microorganisms needs investigated illustrate impact emissions; (3) combined contaminant sorption experiments conducted large-scale applications; (4) more reveal benefits coupling with anaerobic digestion technology. suggested it would valuable create database contains detailed information how got different sources, preparation conditions can applied field.
