The Influence of pH on Electrochemical Behavior of Nicotine- Clay based Electrodes
(Belgrade : International Institute for the Science of Sintering (IISS), 2021)
Montmorillonite based clay was acid activated. Nicotine was adsorbed on untreated
and acid activated clay from its aqueous solution at either pH=6 or pH=9.26 (unadjusted pH
solution). The XRD analysis revealed that the ...
