Abstract
The changes in the radical concentration and the development of the po rous structure of the activated carbon obtained by pyrolysis in the pr esence of water vapor of various agricultural by-products are investig ated by EPR spectroscopy and argon thermal desorption. It was found th at they depend on the nature of the raw material and the final tempera ture of the process. A similarity was established between the dynamics of the change in radical concentration and the development of new sur faces of some of the activated carbons.
