INFLUENCE OF SURFACTANT AND ULTRASONIC TREATMENT ON THE SORPTION CHARACTERISTICS OF THE “POROUS CARBON – NICKEL HYDROXIDE” SYSTEM

Abstract

In this paper we studied the variation of sorption characteristics of nanostructured composites prepared by precipitation of nickel hydroxide from aqueous sodium chloride in alkaline medium on the surface of a highly porous carbon matrix "Kemer-8", with the addition of surfactants and / or ultrasonic treatment during synthesis. It is shown that the effect of the surfactant has a non-trivial character: at significant concentrations sorption characteristics of the system increase, while at small concentrations they decrease. The use of ultrasound in the synthesis of leads to deterioration of sorption characteristics.
