SORPTION PARAMETERS OF «NI(OH)2 – POROUS CARBON» NANOSTRUCTURED COMPOSITES
Abstract
The paper studies the variation in sorption parameters of nano-structured composites received by sedimentation of nickel hydroxide from a water solution of chloride in the alkaline environment on the surface of high-porous carbon matrixes «Karbonizat-3» and «Kemerit-8». It is shown, that the addition of a relatively small amount of nickel hydroxide (10 % onof the weight) results in double reduction of the surface area and volume of the pores. The further increase of Ni (OH)2content in the composite tends to increase sorption parameters. In composites on the basis of «Kemerit-8» matrix the surface area and volume of mesopores increase, and in composites on the basis of «Karbonizat-3» matrix– that of micropores increases.
