Turbidity spectrum method for the characterization of ill-defined disperse systems

Turbidity spectrum method for the characterization of ill-defined disperse systems 

The main premises of this technique are given in the monograph (Klenin et al., 1977a) with calibrations of all the characteristic functions for inonodisperse, spherical particles within wide ranges of a Euid m computed with the use of Mie s theory. Since then, new results have been obtained concerning the problem of phase sepsu ation in polymer systems. 

Within a restricted wavelength range AA, the spectral dependence of turbidity is expressed by Angstrom s (1929) equation (van de llulst, 1957 Heller et al., 1962 Kcrker, 1969) 

Neglecting the dispersion of the refractive index of both the dispersed phase and disperse medium (see Equations 41, 38, 91) (Slulskcr and Marikhin, 1961), 

According to Equations 68 and 96, in Rayleigh-Debye s approximation (KhlebUsov and Shchyogolev, 1977a Khlebtsov et aJ., 1977)
