【 摘 要 】

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.
