Effect of mechanochemical modification on the surfactant and structural properties of humic and himatomelanic acids

Resumo

The structural properties of humic and himatomelanic acids are studied by means of ¹Н NMR spectroscopy and differential thermal analysis after mechanochemical modification of peat. The relationship between the structural modification of humic and himatomelanic acids and their surfactant properties in aqueous solutions is established. It is shown that the critical micelle concentration of transformed himatomelanic acids is halved in comparison to the initial sample, while the adsorption equilibrium constant grows by 9 times.
