Abstract: KEYWORDSSorption capacity of single-walled carbon nanotubes, detonated nanodiamonds and graphene to humic substances was studied by radiotracer method. Tritium labeled brown coal humic acids and fulvic acids separated from Suwannee River were used as sorbates. Adsorption isotherms were described by Langmuir equation. It was found that, for all tested carbon-based nanomaterials, adsorption of coal humic acids is higher than of river fulvic acids. Adsorption capacity of nanomaterials in attitude to humic substan… Show more

“…8. Here, we confirmed our previous hypothesis that ND coverage by low-molecular weight physiologically active compounds does not lead to high aggregation of ND particles, unlike coverage with macromolecules that form polylayers on ND surfaces, and result in high aggregation of nanoparticles [31,33]. The role of electrostatic interactions between the surface groups of ND and sorbate (propidium iodide) was studied by Gibson et al [45].…”

“…Removal or separation of large quantity of CO2 released by industries is inevitable. Many methods are employed to separate CO2 from entering into atmosphere, but sorption method [3] was found to be more economical and simplest [4]. Zeolites, persovskites, hydrotalicites, soda lime, polymeric membranes, fcu-MOF based rare-earth metals and also metal oxides like lithium zirconates, lithium potassium zirconates, sodium metasilicates, etc., are used as a sorbents to capture or separate CO2 from the atmosphere [5][6][7][8].…”

“…Important characteristics of HS are the ability to form complexes with metal ions and hydrous oxides and interact with clay minerals and organic compounds such as alkanes, fatty acids, dialkyl phthalates, and pesticides. In fact HS have a variety of functional groups [8] and can form strong complexes with metal ions, affecting their speciation, mobilization, and toxicity [9,10]. The interaction of HS with oxide and clay minerals can modify their physicochemical characteristics and affect the way that these substances interact with water, metal ions, and other organic molecules [11,12].…”

“…A number of studies have shown that HS are very complex and heterogeneous molecular systems [8,[14][15][16]. This implies the need of using complementary analytical techniques to infer the chemical properties of such substances; elemental analysis and in particular the H/C and C/N atomic ratios are frequently used to indicate organic matter source, degree of condensation, and the environmental conditions under which the HS were generated [8,17,18].…”
