respectively.
pHzpc value of the carbon was measured by using Malvern Nanosize ZS-3600 zetasizer.
A
scanning electron microscope was used to examine the surface morphology of the grape stalk and activated carbons obtained.
The samples for SEM analysis were prepared by sputter-coating the surfaces with
A The elemental composition was analyzed by EDX.
Particle size distribution and elemental analysis of the samples were performed using
Malvern Master Sizer 3000 and LECO CHNS 932 Elemental Analyzer,
