چکیده مقاله:

A new sorbent composed of 3-aminopropyltriethoxy-silane-coated magnetic nanoparticles, functionalized with rhodium(III) porphyrin complex was synthesized and characterized by elemental analysis, X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Fourier Transform Infrared Spectroscopy (FT-IR) and ThermoGravimetric Analysis (TGA). The effect of some co-existing anions present in aqueous solutions, pH, sorbent dosage and contact time on the thiocyanate removal was investigated. Thiocyanate adsorbing material was regenerated with 15 mM NaOH up to 97.0 %. The effectiveness and feasibility of the proposed sorbent for removal of thiocyanate ions from aqueous solutions is proved.

Removal of thiocyanate ions from aqueous solutions using polypyrrole and polyaniline conducting electroactive polymers

Polypyrrole (PPy/Cl) and polyaniline (PAni/Cl) synthesized chemically onto sawdust (SD)was used for removal of thiocyanate (SCN-) ions from aqueous solutions. The effect of someimportant parameters such as pH, initial concentration, sorbent dosage, and contact time onuptake of SCN- was investigated. PPy/SD was found to be much more effective sorbent thanPAni/SD for uptake SCN- from aqueous solu...

Rotational dynamics of thiocyanate ions in highly concentrated aqueous solutions.

The thiocyanate (SCN(-)) anion is known as one of the best denaturants, which is also capable of breaking the hydrogen-bond network of water and destabilizing native structures of proteins. Despite prolonged efforts to understand the underlying mechanism of such Hofmeister effects, detailed dynamics of the ions in a highly concentrated solution have not been fully elucidated yet. Here, we used ...
