Ah&act-Surface acidity of charcoals prepared by the carbonisation of PVDC, PVC, Saran, PF and UF polymers has been determined by titration with sodium hydroxide and sodium ethoxide. The surface acidity as determined by titration with 0.2N sodium hydroxide solution is found to be almost exactly equiv

Interaction of poIymer charcoais with bromine in aqueous sofutions results in the conversion of bromine into HBr and its fixation by the charcoals. The amount of bromine converted into HBr is related to the surface acidity of the char while the amount fixed depends upon the nature of the char and th
Ah&act-Eleven different chars prepared from four polymer precursors viz. polyfurfuryl alcohol (PF), polyvinylidene chloride (PVDC), polyvinyl chloride (PVC) and urea formaldehyde resin (UF) have been studied for their surface complexes by evacuating to 1200°C in steps. The amount of oxygen and hydro
## Abstract Adsorption of albumin, γ‐globulin, and fibrinogen from solution, under both static and flow conditions, onto several hydrophobic polymers was studied using internal reflection infrared spectroscopy. Isotherm curves experimentally found were consistant with Langmuir type adsorption. The
