Electrochemical properties of carbonized bentonite

Organomodified bentonites were obtained by modification of bentonite clay from local mine Bogovina, with four different alkylammonium ions in the amounts that correspond to cation exchange capacity. Carbonized bentonites, pyrolyzing organomodified flow nitrogen, characterized using XRD, low-temperature N2 physisorption and Raman spectroscopy. Structural textural properties carbonized depended on arrangement cations paternal bentonite, while spectroscopy confirmed presence amorphous carbon. The used for carbon paste electrode. modified electrodes investigated cyclic voltammetry electrochemical impedance electrosorption chloride sulfate anions was studied chronocoulometry. results interpreted terms surface groups bentonites.
