Research of the Influence of Electromagnetic Field on the Optical Properties and Stability of Aluminum Hydroxide Sol

Influence of a high-frequency electromagnetic field on optical properties of aluminum hydroxide sol, and also on its stability is shown. As a result of electromagnetic influence light dispersion increases, рН changes what indicates a change in a size of colloidal particles and in a structure of EDL at the interface. The electromagnetic field significantly reduces the rate of sol#s coagulation, and also causes peptization of Al(OH)3dregs.
Key words: coagulation, electromagnetic field, sol, optical density, length of a wave, aluminum hydroxide.
