ABSTRACT:
A gravimetric method for determining the iodine adsorption number of carbon black is disclosed. The concentration of an accurately weighed iodine solution is determined by titrating with a standardized titrant and determining the concentration of the iodine solution by the weight of the standardized titrant needed to reach the titration endpoint. An appropriate amount of accurately weighed iodine solution is mixed with an accurately weighed amount of carbon black, and the mixture is equilibrated. The concentration of the resulting supernatant is determined by determining the weight of the standardized titrant needed to reach the titration endpoint. The iodine adsorption number is then determined based on the gravimetrically determined concentrations of the solutions. Preferably, the method is semi-or fully automated, and an apparatus for accomplishing the same is disclosed.
