Specific surface areas of silica gel packings could'be determined by an on-column acid-base titration method. Silica gel materials packed in microcolumns were equilibrated with sodium hydrogencarbonate, followed by titration with hydrochloric acid. The effluents from the columns were monitored by an

powders prepared by thermal decomposition of nitrate (TDN) and by precipitation in aqueous solution (PAS) have been investigated in relation with the zinc-ion adsorption (ZIA) method of in situ measurement of specific areas at the solid-liquid interface. The ZIA method seems feasible with dry TDN po
