Experimental evidence is presented for the existence of quinone, aromatic ether, carboxylic acid and phenol groups on the surface of a graphitized carbon black (GCB), that is P-33 (2700°C). This evidence has been achieved by using polarographic analysis of a slurry of GCB particles. Polarographic analysis has been also performed for ungraphitized P-33. By comparison, it appears that the heating at 2700°C does not remarkably change the nature and the amount of chemical groups chemically bound to the surface of the carbon black. © 1982.

Abstract
Experimental evidence is presented for the existence of quinone, aromatic ether, carboxylic acid and phenol groups on the surface of a graphitized carbon black (GCB), that is P-33 (2700°C). This evidence has been achieved by using polarographic analysis of a slurry of GCB particles. Polarographic analysis has been also performed for ungraphitized P-33. By comparison, it appears that the heating at 2700°C does not remarkably change the nature and the amount of chemical groups chemically bound to the surface of the carbon black. © 1982.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
