MOMENT ANALYSIS OF CONCENTRATION DECAY IN A BATCH ADSORPTION VESSEL

[摘要] References(14)Cited-By(9)Moment equations are derived for concentration decay curves of tracer in a well-mixed batch slurry adsorber. This gives relations between the rate parameters for mass transfer and adsorption and the moments of the experimentally measurable curves. The results provide a method for measuring rate parameters in slurry systems. The method is illustrated by evaluating fluid-to-particle mass transfer coefficients and effective diffusivities from experimental data for the adsorption of dodecylbenzenesulfonate in slurries of bone char particles.
