Latex Particle Size Distribution from Turbidimetry Using Inversion Techniques

Abstract

A method is reported for the estimation of the size distribution of particle suspensions from spectral turbidity data. The proposed method is based on existing solutions to Fredholm integral equations of the first kind and the generalized cross validation technique. The capabilities of the proposed method are experimentally demonstrated through the recovery of the particle size distribution of polystyrene, poly(methyl methacrylate), and several copolymer latices. It is shown that the proposed method yields good recoveries of the shapes and the averages of the particle size distributions.
