Abstract
Physico-chemical parameters of the synthesis of carbonized sorbents based on plant raw material are investigated along with the properties of these sorbents. The data of IR Fourier, ESR spectroscopy and electron microscopy are reported. It is stated that carbonized sorbents possess high specific surface and porosity. Carboxylic, carbonyl, hydroxyl groups are detected on the surface of the synthesized sorbents. It is assumed that high sorption ability with respect to Co, Ni, Pb, Cd, Cu ions is connected with the formation of chelate complexes.
