in this research, the interaction of hexadecyl trimahyl ammonium bromide (htab) with enzyme ureasehas been investigated comprehensively at different experimental conditions such as ionic strength, proteinconcentration using ion selective membrane electrode of surfactants. the obtained binding isotherms frompotentiometnc studies have been analyzed by different theories such as wyman binding pote...

Preparation and performance of a cost effective silver sulfide based bromide selective membrane is described. A solid contact between membrane and body of the electrode was examined as an ion-selective electrode by determining S 2and Br ions by direct potentiometry. A linear response to bromide ion from 2 x 10 -5 to 10 -1 M with a slope of 57.3 mV per decade [Br ] is observed. The membrane has ...
