Determination of Adsorption Parameters of Active Carbon Filters Measuring Only the Beginning of the Breakthrough Curve 970112
The adsorbed mass is an important parameter for the characterization of adsorptive filters. For its calculation it is necessary to determine the breakthrough versus time for a given upstream concentration. In order to reduce testing time, emissions and the amount of contaminants required, an evaluation method was developed that allow prediction of the breakthrough curve by extrapolating an aborted measurement. This new method reduces the amount of contaminants by more than 80%. Two additional parameters, which describe the characteristics of an adsorptive filter, result from the evaluation procedure.
