Abstract
The aim of this work is to establish the specific features of the adsorption capacity of thermally modified hazelnut shells with respect to Ni2+ ions at different temperatures. Titrimetric, spectrophotometric, atomic-adsorption methods of investigation, optical microscopy, X-ray analysis were used in the work. It is established that the sorption process is endothermic; the time for achieving sorption equilibrium reaches 40 minutes. The article may be of interest to specialists in the field of obtaining new adsorbents using vegetable production waste. The article was prepared within development program of the Flagship Regional University on the basis of Belgorod State Technological University named after V.G. Shukhov, using equipment of High Technology Center at BSTU named after V.G. Shukhov.
