Electron transfer mediated by iron minerals is considered as a critical redox step for the dynamics of pollutants in soil. Herein, we explored reduction process Cr(VI) with different crystalline ferric oxyhydroxides presence pyrogenic carbon (biochar). Both low- and high-crystallinity induced immobilization mainly via sorption process, limited process. However, was inspired copresence biochar. Low-crystallinity oxyhydroxide had an intense chemical combination biochar strong inner-sphere complexation, leading to indirect electron route reduction, that is, first transferred from mineral through C–O–Fe binding then Fe(III)/Fe(II) transformation on oxyhydroxides. With increasing crystallinity oxyhydroxides, direct between became main avenue reduction. The suppressed due less Cr(VI), biochar, higher stability. This study demonstrates mechanisms involving change crystallization which would affect geochemical contaminants carbon.

Dissolved organic matter (DOM) contains complex molecular compounds that dominate its heterogeneous dynamics and behaviors in aquatic environments. Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) with ultra-high resolution has proven to be effective characterizing DOM. However, a systematic summary of molecular-level compositions DOM natural engineered water systems remains insufficient. This study provides critical review characterization by FTICR-MS, emphasis on composition diversity, chemical properties, transformation, the systems. First, FTICR-MS strategies for are introduced data interpretation collaborative analysis complementary datasets (e.g. spectroscopic data). Second, characteristics, including spatiotemporal distribution, photochemical activity, microbial modification, interface adsorption environments were comprehensively summarized based current findings. Third, changes caused different treatment methods reviewed highlight variation, reaction, transformation focusing results. Finally, we limitations, biases, future directions extended studies natural/engineered-derived behavior. application favorable understanding chemistry

Biochar-derived dissolved black carbon (DBC) molecules are dependent on the BC formation temperature and affect fate of emerging contaminants in waters, such as polyvinyl chloride microplastic (MPPVC). However, temperature-dependent evolution MPPVC-interaction DBC remain unclear. Herein, we propose a novel DBC-MPPVC interaction mechanism by systematically interpreting heterogeneous correlations, sequential responses, synergistic relationships thousands their linking functional groups. Two-dimensional correlation spectroscopy was proposed to combine Fourier transform–ion cyclotron resonance mass spectrometry spectroscopic datasets. Increased caused diverse fluorophores, accompanied molecular transformation from saturation/reduction unsaturation/oxidation with high oxidation states, especially for acidic The response detected via negative-/positive-ion electrospray ionization sequentially occurred unsaturated hydrocarbons → lignin-like condensed aromatic lipid-/aliphatic-/peptide-like tannin-like carbohydrate-like molecules. changes induced MPPVC were closely coordinated, contributing most interaction. Functional groups m/z < 500 showed phenol/aromatic ether C–O, alkene C═C/amide C═O polysaccharides C–O alcohol/ether/carbohydrate These findings help elucidate critical role DBCs MP environmental behaviors.

The role of modified biochar in enhancing phosphorus (P) availability is gaining attention as an environmentally friendly approach to address soil P deficiency, a global agricultural challenge. Traditional phosphatic fertilizers, while essential for crop yield, are costly and detrimental owing fixation leaching. Modified presents promising alternative with improved properties such increased porosity, surface area, cation exchange capacity. This review delves into the variability based on source production methods how these can be optimized effective adsorption. By adjusting pH levels functional groups align phosphate’s zero point charge, we enhance biochar’s ability adsorb retain P, thereby increasing its bioavailability plants. integration nanotechnology advanced characterization techniques aids understanding structural nuances interactions phosphorus. offers multiple benefits: it enables farmers use more efficiently, reducing need traditional fertilizers minimizing environmental impacts, greenhouse gas emissions also identifies existing research gaps future opportunities further modifications. These findings emphasize significant potential sustainable agriculture.
