Carbon blacks were treated with P,S, in the 60 to 500Β°C temperature range for increasing times of treatment of up to four hours. A series of experimental methods was applied to follow the formation of sulfur surface derivatives: elemental analysis, basic surface groups analysis by back-titration, ES
