The Determination of Size Distribution of Particles in Suspension by a Diffusion Technique

Abstract

Summary Under the assumption of a logarithmic particle-size distribution, the geometric mean radius r̄ and the geometric standard deviation σ can be determined by means of radial diffusion transport and wall adsorption within a capillary. The possibility of simultaneous sedimentation is taken into account. The best fit of the experimental results to calculated curves is shown to confirm earlier estimates of the size of „radiocolloids" and Al2O3-powder.
