The properties of carbon nanotubes after different chemical treatments are considered. After chemical treatment of powders of initial carbon nanotubes, the content of such an impurity as the unburned rest is decreased from 13.5% to 0.77% that results in increase in adsorption–structural characteristics. As a result of investigations of influence of temperature on carbon nanotubes, the mechanism of their oxidation by oxygen of air after various chemical treatments is investigated. As shown, after modification of a surface of powders of initial carbon nanotubes and nanotubes subjected to additional chemical treatment with ferromagnetic iron particles, their magnetic characteristics increase by a factor of ten. As revealed, after modification of a surface of carbon-nanotube samples with ferromagnetic iron particles, their adsorption–structural characteristics are dropped.
