Theoretical Investigations on the Light Scattering of Colloidal Spheres. XII. The Determination of Size Distribution Curves from Turbidity Spectra

Abstract

The theory of a method is outlined which gives size distribution curves in heterodisperse systems of non-absorbing colloidal and small microscopic spheres from measurements of turbidity spectra. The assumption is made that the distribution follows a function previously given which closely approximates that commonly found in emulsions. All the numerical data necessary for practical application of the method are provided for the relative refractive indices m=1.05 (0.05) 1.30. They were obtained from the Mie theory. The method may be used independently, but is particularly useful in conjunction with an alternate method described in a previous publication (XI).
