Transmittancy of commercial sugar liquors: dependence on concentration of total solids

Abstract

The dependence of the transmi ttancy of a commer cial su gar liquor on the concentration of total solids does not in gf'neral foll ow Beer's law. This behavior is attributed to t he presence of apprecia ble light-scattering m aterial in t he solution. A linear dependence has been found to relate the concentration with the reciprocal of a:, the latter being; ucfincd as equal to ( -log T .) /bc, where T . is the transm ittancy, b t he cell length, and c the concentrat ion of total solids. The intercept at c= O in a plot of l /a; versus c is equal i n magn itude t.o t he limiting slope of the Beer's law plot.

Light scattering by commercial sugar solutions

“…When the system both absorbs and scatters light, then one writes [8] −logTbc=a*,in which a * is the attenuation index.…”
