Adsorption of phenol and benzoic acid from dilute aqueous solution onto a macroreticular resin

Abstract Radiolabeled solutes were used to obtain equilibrium adsorption data for the uptake of benzoic acid and phenol by a macroreticular resin (Amberlite XAD-8) from dilute aqueous solutions. Phenol was studied at 0, 25, and 70°C, and benzoic acid was studied at 25°C. The phenol data, which covered a wide concentration range, was modeled with less than 5% error using a three parameter adsorption equation.

Determination of self diffusion coefficients using the radial distribution function

A new diffusion equation was developed for predicting self-diffusion coefficients in liquid metals. The new model makes use of fluctuation distances obtained from radial distribution curves to predict diffusivities accurately over a wide temperature range. Fluctuation distances used in the new model are greater than values used in other fluctuation models.
