The research involved a study of factors effecting adsorption of phenol from aqueous solution on six solids of varying polarity including polymers of known surface area. The amount of phenol adsorbed over a wide range of phenol concentration was determined by a gas chromatographic technique. The critical surface tensions of the polymers were determined by contact angle measurements. Reflection infrared spectra were obtained on the powdered solids. Anomalously large quantities of phenol were taken up by microcrystalline Nylon presumably by an absorption process. (Author)
