Microdetermination Of Some Organic Nitriles Using The Cyanide Ion Selective Electrode
Hassan, S. S. M. [سعد السيد محمد حسن] ( Qatar University , 1985 , Article)The response characteristics of the solid state cyanide ion selective electrode toward some organic nitriles are investigated. In 10 M KOH solution, the electrode exhibits near Nemstian response over the range of 10~2 to ... -
A New Liquid Membrane Electrode For Selective Determination Of Caffeine
Hassan, S. S. M. [سعد السيد محمد حسن]; Saoudi, M. M. ( Qatar University , 1984 , Article)A new liquid membrane electrode for caffeine prepared from a solution of caffeine-picrylsulfonate ion-pair complex in n-octanol is developed. It exhibits Nernstian response in the range of 10'2 to lO^M caffeine with a ... -
