  • Interfacial interactions of bare and functionalized

    BNPs favourably attracted to sand surface at pH 3.5. • Humic acid at concentration >1 mg/L reduced the retention of BNPs by sand. • Presence of Ca 2+ ions will also suppress the retention of BNPs by sand.. Both humic acid and PSS molecules hindered the retention of PSS-NPs by sand.

  • Humic acid-, ferrihydrite-, and aluminosilicate-coated

    The amount of humic acid that we could coat onto the sand was around 1 mg/g of sand (), which is similar to the result obtained using sol-gel immobilization .Koopal et al. reported a surface coverage of humic acid of 56 mg/g, but used a much smaller-sized silica support than we did. On a per surface area basis, our 26 mg/m 2 compares with 1.1 mg/m 2 from Koopal et al. .

  • Humic substance Wikipedia

    Humic substances are organic compounds that are important components of humus, the major organic fraction of soil, peat, and coal (and also a constituent of many upland streams, dystrophic lakes, and ocean water).For a long era in the 19th and 20th centuries, humic substances were often viewed through a lens of acid–base theory that described humic acids, as organic acids

  • Enhanced distribution of humic acid-modified nanoscale

    The amount of Mg present on the silica sand with humic acid-modified NMgOs was determined to be 5.78%, while only 0.19% of Mg was detected on the sand with unmodified NMgOs, demonstrating much better mobility of the humic acid-modified NMgOs. This result is consistent with the breakthrough curves of Mg released from unmodified NMgOs and humic

  • Humic acid-modified silica as a model aquifer material

    The sorption behavior of nonionic organic chemicals on humic acid-modified silica was examined to assess its possible use as a simplified model of natural low organic carbon aquifer materials. Column and batch sorption experiments were conducted on humic acid-coated silica (0.073% organic carbon), using tetrachloroethylene (PCE) and 1

  • Interaction of Fullerene (C60) Nanoparticles with Humic

    The deposition kinetics of fullerene (C60) nanoparticles onto bare silica surfaces and surfaces precoated with humic acid and alginate are investigated over a range of monovalent (NaCl) and divalent (CaCl2) salt concentrations using a quartz crystal microbalance. Because simultaneous aggregation of the fullerene nanoparticles occurs, especially at higher electrolyte concentrations, we
