Graphite paste electrodes are made by mixing natural graphite (65–80%), an organic binder such as wax, resin or a polymer (~13%) and clay or spindle oil (8–30%) (Annu et al., 2020). Graphite reinforcement carbon is used in pencil lead, which is the same material used as ...
A study of the pH influence is highly significant even for the potential antioxidant activity of the NG, due to the fact that pH is influencing even the active compound mesomeric structure. It is known that H+ ionization from phenolic-OH, especially in protic solvents, is associated with ...
An araldite mixture (epoxy resin, 1:1) [16,41,43,44,45], bentonite [38,39], or cyanoacrylate glue [40] was used to fix the graphite lead into the support. Other PGEs were obtained by covering a part of the graphite lead with nail polish [53] or with Teflon tape [20,54,55,56...
