X-ray spectral studies of sorption mechanism on the surface of iron-manganese nodules

Abstract

A method of analyzing the changes in the state of the sorbent surface depending on the time of sorption of petroleum products from aqueous solutions for different granulometric composition of the initial sorbent using coherent scattered X-ray radiation has been developed. The theoretical basis and experimental estimates of changes in the angle of coherently scattered photons from the sorbent surface are given. It is obtained that the angle of coherent scattering of photons depends on the class of sor-bent coarseness. In the process of sorption there is a change in the surface structure, which leads to a change in the scattering angle. Thus, knowing the angle of scattered radiation, it is possible to determine the type of the surface of any porous sorbent, as well as to estimate the degree of filling of the surface with the sorbed substance.
