“…For example, the Fe oxides NPs-supported biochar derived from leaves showed efficient removal ability for Cr(VI) and As(V) (Liang et al 2019c;Sahu et al 2019). Pristine or modified biochar derived from leaves also acted as an excellent adsorbent for organic pollutants (Hu et al 2019;Ma et al 2019;Vyavahare et al 2019). Additionally, leaves-derived biochar could serve as a promising soil conditioner to increase agricultural productivity (Konaka et al 2019).…”

Biochar, derived from thermal pyrolysis of biomass, has been regarded as a low-cost, sustainable and beneficial material and widely applied in agriculture, environment and energy during the last two decades. To elucidate the research status timely and future trends in biochar field, CiteSpace is used to systematically analyze the related literature retrieved from the Web of Science core collection in 2019. Based on the keywords clustering analysis, it was found that "biochar production", "organic pollutants removal", "heavy metals immobilization", "bioremediation" were the main hotspots in research covering biochar. "Bioremediation" is an emerging topic and deserves extensive attention due to its highly effective and environmentally friendly treatment of pollutants. Improving the phytoremediation effect, immobilizing functional microorganisms on biochar, and using microorganisms as raw materials to produce biochar were the common methods of biochar-assisted bioremediation. While studies focused on "soil quality and plant growth" and "biochar and global climate change" decreased, investigations concentrated in the toxicity of biochar to soil biota and ruminants are sustainably growing. Research on direct and catalytic thermal pyrolysis of green waste (mainly microalgae) for biofuels (bio-oil, biodiesel, syngas, etc.) and biochar production is increasing. Converting municipal wastes (e.g., sewage sludge, fallen leaves) into biochar through pyrolysis was a suitable treatment for municipal waste and became a popular topic in recent time. Moreover, the biochar produced from these municipal wastes exhibited excellent performance in the removal of pollutants from wastewater and soil. This review may help to identify future directions in biochar research and applications.

“…The toxicity analysis of MnF‐PANI‐NC was performed by a phytotoxicity study. [ 44 ] In this case, a seed germination test was conducted on Vigna mungo seeds to check the extent of toxicity of the composite. In a typical experiment, a 0.2 g/L dose of MnF‐PANI‐NC was added to 200 ml of DI water and the mix was sonicated for 15 min.…”

Remediation of toxic dyes from an aqua matrix using novel nanocomposites as adsorbent is an attractive yet challenging task, especially when the adsorption process needs to be operated at near-neutral solution pH. Recently, conducting polymer-based novel nanocomposites have been studied widely for environmental remediation because of their high distinctive surface area, mesoporous nature, easy synthesis process, availability of the low-cost monomer, and comprehensive range of functionality. This research deals with the fabrication and application of manganese ferrite and polyaniline nanocomposite (MnF-PANI-NC) for the ultrasound-assisted adsorption of methyl red (MR) and congo red (CR) dye from binary dye solution at neutral pH. The X-ray diffraction pattern of MnF-PANI-NC confirmed the successful impregnation of manganese ferrite onto polyaniline, and the field emission gun scanning electron microscopy and transmission electron microscopy images revealed the nanoscale formation of this composite. The saturation magnetization of~20 emu/g endorses the easy magnetic separation of MnF-PANI-NC from dye solution. MnF-PANI-NC has revealed higher adsorptive affinity towards MR and CR dye concerning pure PANI and pure MnF nanoparticles at near-neutral solution pH. Assimilation of ultrasound wavse in this adsorption procedure improved the mass transfer rate significantly, and within 6 min of reaction more than 95% of MR and CR dye removal was achieved. Ultrasound waves also enhanced the equilibrium dye uptake efficiency (more than 95%) of MnF-PANI-NC compared to the adsorption reaction by overhead stirring (40-50%) and shaking (40-60%) for both MR and CR dyes. Kinetic modeling of the experimental data revealed accurate fitting of the pseudo-second-order model in association with intraparticle diffusion. Binary dye adsorption onto MnF-PANI-NC obeyed the Langmuir isotherm model accurately, and maximum adsorption capacities of 294.12 and 317.46 mg/g were observed for MR and CR dyes, respectively.

“…Para pH mayores al pHPZC, predomina una carga negativa y a menores predominan cargas positivas (Muñiz et al, 2009). En ese sentido, esta situación favorece, a través de la atracción electrostática, la adsorción de cationes y aniones respectivamente debido a las fuerzas de atracción entre la carga opuesta del adsorbente (Vyavahare et al, 2019). En la figura 4 se muestran las imágenes de microscopia electrónica de emisión de campo (FESEM) de la muestra CC-B, a magnificaciones de 1000x y 500x.…”

Se produjo biocarbón a partir de residuos de coronta de maíz (Zea mays) para remover plomo de soluciones acuosas. La carbonización del residuo se realizó a 600 °C por 2 h a 1 atmosfera de nitrógeno controlada. Se realizaron análisis texturales, morfológicos y estructurales para caracterizar el material. De los datos de la isoterma de adsorción de N2, el material mostró una estructura microporosa de 144,13 m 2 /g de área superficial. Se realizaron experimentos de adsorción de Pb 2+ en equilibrio y cinética, donde los datos de equilibrio se ajustan mejor al modelo de Dubinin-Radushkevich (R 2 ≥ 0,990) con capacidad de adsorción máxima de 12,16 mg/g con. Asimismo, para los datos de cinética, el modelo con mejor ajuste fue el de Elovich (R 2 ≥ 0,994). Sin embargo, la cinética de adsorción también se ajustó a los modelos de Pseudo-Primer orden (R 2 ≥ 0,990) y Pseudo-Segundo orden (R 2 ≥ 0,992), con valores de adsorción de 10,54 mg/g y 15,59 mg/g respectivamente. El análisis de la espectrometría de energía dispersiva (EDS), después de las pruebas de adsorción detectaron la presencia de Pb 2+ en la estructura del biocarbón. La coronta de maíz tiene un potencial uso para la producción de biocarbón y la remoción de Pb 2+ , demostrando ser eficiente.
