This study presents a novel approach for the simultaneous identification and quantification of extractable chlorinated organic carriers (COCs) from diverse materials, including textiles, foam leather. COCs, valued chemical synthesis, dye transfer solvents formulations. In this work, dichloromethane under ultrasonic conditions at 25 °C 30 minutes was employed extraction COCs. Gas chromatography mass spectrometry (GC-MS) utilizing DB-5MS column facilitated separation detection target analytes. SIM ionization mode utilized with qualifier ions detection. Optimization parameters such as extractant type, method, time resulted in high recoveries ranging 95% to 105%. The calibration curve exhibited range 5 120 ng mL−1 regression values 0.996–0.998. method demonstrated excellent precision relative standard deviations (RSD) below 10% test specimens pure standards. Limits (LODs) 0.1 mL−1, indicating sensitivity. Application developed real successfully detected COCs concentrations 2.60 9.94 affirming its effectiveness environmental monitoring risk assessment.

Biochar/Biopolymer Composites for In-Situ Groundwater Remediation

Опубликована: Июнь 20, 2024

(max 200 words): The contamination of groundwater is a serious concern for ecosystems and human health. In this regard, biochar represents promising low-cost sustainable material in-situ remediation. Herein, waste biomass energy production process derived from pine wood gasification at 950°C was used as active carbonaceous in combination with different biopolymers: chitosan (CS), alginate (ALG), potato starch (PST), carboxymethylcellulose (CMC) to produce BC@biopolymer composite materials. Different concentrations (0.3–1.0 g·L-1) biopolymers (0.2–20.0 were tested blending mode simple straightforward strategy obtain BC composites. Scanning electron microscopy (FE-SEM), UV-Visible, infrared (FT-IR) spectroscopy, specific surface area (BET method), pore volume, size distribution (textural parameters), dynamic light scattering (DLS), ζ-potential investigate the chemical structure, stability, assess interaction among counterparts. On optimized formulations, breakthrough tests batch adsorption isotherms on trichloroethylene (TCE) model contaminant performed evaluate capability composites be delivered through porous medium determining transport properties, (hydrodynamic dispersion retention percentage, capacity). This biopolymer-modified holds significant promise effective solution address various pollution challenges.

Effective Microbial Strategies to Remediate Contaminated Agricultural Soils and Conserve Functions

Agronomy, Год журнала: 2024, Номер 14(11), С. 2637 - 2637

Опубликована: Ноя. 8, 2024

The growing global emphasis on sustainable agriculture has brought increased attention to the health and productivity of soils, especially through lens soil microbiology. Microbial communities in are essential for nutrient cycling, organic matter decomposition, maintaining overall health. However, agricultural practices, including synthetic fertilizers intensive farming, have led short time impacts these microbial ecosystems, potentially threatening fertility environmental quality. Agricultural expansion food production generate waste chemical inputs, such as heavy metals, pesticides, herbicides, leading significant contamination. This scenario requires implementation remediation strategies that both energy efficient. In this context, microbiological processes present a much promising approach mitigating pollution. Techniques bioremediation, which harness natural metabolic capabilities microorganisms, bioaugmentation, involves introduction specific strains increase degradation processes, being explored. These approaches vital restoring health, contributing conservation biodiversity, improving promoting long-term productivity.
