摘要：
The colloid-chemical properties of humic acids (HAs) were studied depending on the mechanochemical modification of their structure. An increase in the amount of acidic ionogenic groups and hydrophilic fragments in the composition of modified HAs facilitated a decrease in the excess energy of surface molecules. In an alkaline solution, two types of colloids characterized by a decrease in the energy of adsorption and the constant of adsorption equilibrium were formed as the concentration of HAs was increased.
