Uncertainty in Determining the Apparent Specific Surface Area of Particulate Matter Based on the Power Law Model

The paper analyzes the uncertainty of the determination of the apparent specific surface area (SSA) of particulate matter using the power model of particle size distribution. It compares this method with selected experimental procedures in terms of measurement uncertainty. It shows that the presented measurement uncertainty is higher due to the sensitivity of the computational model to the input parameters, therefore the method is particularly suitable for rapid estimates of the SSA of simple non-porous particles of particulate matter.
