Electrochemical characteristics and catalytic ability of oxidized synthetic charcoals modified with transition metal ions (Fe3+, Cu2+, Zn2+, Ni2+) in oxygen-containing solutions have been studied. Two approaches to elimination of toxis substances from model solution and blood plasma have been examined using creatinine as an example: electrochemical oxidation in fluidized-bed layer of non-modified activated SCN adsorbent and specific adsorption on the surface of modified SCNo ones. The results of investigation have shown that effectivity of creatinine elimination is the same in both cases and depends on the external potential and type of modifying ion.
