Uticaj modifikacije gline na elektrohemijsko ponašanje hinhidrona

Abstract

Glina bogata monmorijonitom iz Vajominga je modifikovana kiselom aktivacijom i procesom pilarenja. Ovako izmenjena glina, kao i polazna glina, je naneta na površinu elektrode od staklatog ugljenika pomoću Nafiona. Aktivnost ovih elektroda je ispitana na primeru redoks para hinon/hidrohinon (Q/QH2) u puferovanom i nepuferovanm rastvoru. Način modifikacije glina je uticao na aktivnost elektroda i mehanizam redoks rekacije

Montmorillonite originated from Wyoming was modified by acid activation and aluminum pillaring process. The samples of clay obtained in this manner, as well as starting clay, were applied at the surface of a glassy carbon electrode by the means of Nafion. The activity of these electrodes was investigated on the redox couple quinone/hydroquinone (Q/QH2) in buffered and unbuffered solutions. The type of clay modification influenced the activity of the electrodes and the mechanism of the redox reaction.
