The properties of ceramic membranes prepared via the sol-gel process can be controlled by varying the suspension and interfacial chemistries of the precursor sols. The Year 1 Progress Report described the effects of changing several variables. This report presents results on the effect of sintering conditions on the properties of unsupported titania membranes. A description of the effect of phosphate addition on the preparation of alumina and titania membranes is also included, although this study is not yet complete. The preparation of silica membranes is also discussed. This second year of work has also included characterization of supported membranes, membranes which have been deposited on a support and then sintered to fix the membranes in place. These studies have involved measurements of the permeability of the supported membranes to various aqueous feed streams utilizing a laboratory scale test apparatus. PH and temperature effects on the flux of water through the membranes is described. Permselectivity measurements utilizing solutions of polyethylene glycol (PEG), bovine serum albumin, and cheesy whey, are also discussed. Because dissolution of membranes at extreme pH values can be a major problem in potential industrial applications, the stability of both unsupported and supported membranes at different pH values was determined. 9 refs., 22 figs.
