Simultaneous adsorption of Cu(II) ions and poly(acrylic acid) on the hybrid carbon-mineral nanocomposites with metallic elements.

In order to propose a novel, effective adsorbent of Cu(II) ions, hybrid carbon-mineral nanocomposites with metallic elements (Mn/Fe in the case of B-6, Mn - B-8) were examined. A combination of mechanochemical and pyrolytic methods was used to obtain these bimodal micro-mesopore systems. First, mechanochemical mixing of phenol-formaldehyde resin and inorganic compounds in a ball mill was carried out.

Study on Adsorption and Aggregation in the Mixed System of Polyacrylamide, Cu(II) Ions and Innovative Carbon-Silica Composite.

The paper presents an original study on adsorption and aggregation phenomena in a mixed system consisting of a macromolecular compound, heavy metal ions and an innovative adsorbent. The authors used ionic polyacrylamides (PAM), Cu(II) ions and carbon-silica composite (C-SiO) in the experiments. Such a system has not yet been described in the literature and therefore, the article is of significant novelty and great importance.

Mechanochemical synthesis of carbon-stabilized Cu/C, Co/C and Ni/C nanocomposites with prolonged resistance to oxidation.

Metal-carbon nanocomposites possess attractive physical-chemical properties compared to their macroscopic counterparts. They are important and unique nanosystems with applications including in the future development of nanomaterial enabled sensors, polymer fillers for electromagnetic radiation shields, and catalysts for various chemical reactions. However, synthesis of these nanocomposites typically employs toxic solvents and hazardous precursors, leading to environmental and health concerns.
