Non-steady-state chambers are commonly used to measure soil and manure emissions of CO2, CH4, N2O. When paired with online gas analyzers, automated non-steady-state (a-NSS) enable high-frequency monitoring greenhouse (GHG) fluxes. Despite their advantages in capturing detailed emission patterns, these systems pose challenges handling large datasets, performing complex flux calculations, scaling results over time. This study introduces a computationally efficient algorithm designed process...
The Cu(II) adsorption from aqueous solutions by magnetic biochar obtained pine needles has been studied means of batch-type experiments. fibers have magnetized prior (pncm: carbonized-magnetized needles) and after oxidation (pncom: carbonized-oxidized-magnetized used as adsorbents to study the presence carboxylic moieties on magnetization following process. effect pH (2–10), initial metal concentration (10−5–9·10−3 mol·L−1) contact time (0–60 min) varying respective parameter, characterized...
Abstract Magnetoactive electrospun fibrous membranes consisting of polyvinylpyrrolidone (PVP), chitosan (CS) and pre‐fabricated, double‐layer oleic acid‐coated magnetite nanoparticles (OA.OA.Fe 3 O 4 ) were fabricated evaluated as new adsorbent materials for the removal recovery uranium (U(VI)) from aqueous solutions. The adsorption has been investigated by batch‐type experiments solid material characterized X‐ray diffraction spectroscopy (XRD), Fourier‐transform infrared (FTIR), scanning...
Pine needle–derived biochars have been prepared and investigated as adsorbent materials for the removal of trivalent samarium (Sm(III)) from aqueous systems. The biochars, which were previously oxidized magnetized), characterized prior after Sm(III) adsorption by Fourier Transform Infrared Spectroscopy (FTIR) X-Ray diffraction (XRD). effect various parameters such metal ion concentration, pH contact time on efficiency has investigated. In addition, competitive experiments carried out...
Removal and recovery of economically important (radio) toxic metals from industrial process wastewaters is particular interest in the frame environmental protection need to cover growing demand for sustainable energy production.Thorium (Th-232) a potential primary fuel nuclear industry, it can be used different reactor types has compared uranium waste disposal proliferation advantages.The present study deals with adsorption/ removal Th(IV) aqueous solutions particularly effect particle size...
Abstract Non‐steady‐state chambers are widely employed for quantifying soil emissions of CO 2 , CH 4 and N O. Automated non‐steady‐state (a‐NSS) chambers, when coupled with online gas analysers, offer the ability to capture high‐frequency measurements greenhouse (GHG) fluxes. While these sampling systems provide valuable insights into GHG emissions, they present post‐measurement challenges, including management extensive datasets, intricate flux calculations, considerations temporal...
Uranium in ground-and wastewater samples has been analyzed by alpha-spectroscopy after pre-concentration and separation means of a chelating resin Lewatit TP 207, following electrodeposition the radioelement on stainless steel discs.The effect amount used uranium recovery spectra quality investigated using 200 mL aliquots groundwater sample.In addition, method successfully applied to detect depleted (DU) contamination obtained from local treatment plant.The radiometric analysis indicated DU...
