From Bulk to Nano: Formation, Features, and Functions of Nano-Black Carbon in Biogeochemical Processes

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(36), P. 15910 - 15925

Published: Aug. 27, 2024

Globally increasing wildfires and widespread applications of biochar have led to a growing amount black carbon (BC) entering terrestrial ecosystems. The significance BC in sequestration, environmental remediation, the agricultural industry has long been recognized. However, formation, features, functions nanosized BC, which is one most active fractions continuum during global climate change, are poorly understood. This review highlights surface reactivity (sorption, redox, heteroaggregation), biotic, abiotic transformations nano-BC, its major differences compared other engineered nanomaterials. Potential nano-BC including suspending agent, soil amendment, nanofertilizer elucidated based on unique properties functions. Future studies suggested develop more reliable detection techniques provide multidimensional information samples, explore critical role promoting planetary health from perspective, extend multifield with lower footprint but higher efficiency.

Efficient removal of emerging pollutant oxytetracycline by cost‐effective biochar–hydroxyapatite composite

Asia-Pacific Journal of Chemical Engineering, Journal Year: 2024, Volume and Issue: 19(6)

Published: July 29, 2024

Abstract Biochar (BC) and hydroxyapatite (HAp) are widely used in environmental remediation due to their high adsorption capacity, porous structure, large specific surface area, chemical stability, non‐toxicity, low solubility. Combining BC HAp is a green effective strategy for creating new adsorbents (BCH) that have synergistic impact on wastewater treatment. In this study, BCH composites derived from apatite ore macadamia nut shells were synthesized by the wet impregnation method remove oxytetracycline (OTC) aqueous solutions. The BC‐HAp composite with ratio of 10:1 (by weight) was most material removing OTC. Redlich–Peterson model achieved highest correlation coefficient among four models tested (Freundlich, Langmuir, Temkin, Redlich–Peterson). maximum capacity calculated Langmuir isotherm 49.59 mg g −1 . It found process significantly affected solution pH. bipolar form drug be OTC ± , solutions pH 6. dominant mechanisms nanocomposites could electrostatic attraction, hydrogen bonding formation, complexation, or ion exchange. Therefore, showed great potential pollutants cost‐effective, environmentally friendly manner.
