web.iyte.edu.tr-Often called Ion Selective Electrodes (ISE) or pIon Electrodes, because the data obtained from them are usually presented as p-functions, (pH, pCa, pNO 3 ) - The general mechanism by which an ion selective potential develops in these devices depends on the nature of the membrane and is entirely different from the
Principle of ion-selective electrode (I.S.E.)
www.sfu.caPrinciple of ion-selective electrode (I.S.E.) An ideal I.S.E. consists of a thin membrane across which only the intended ion can be transported. The transport of ions from a high conc . to a low one through a selective binding with some sites within the membrane creates a potential difference. See Fig. 15-8 for the development of a potential
Ion-Selective Electrode Determination of Fluoride Ion
www.csun.eduThe ion-selective electrode (ISE) typically consists of an inner reference electrode plus a membrane that provides the interface between the sample solution and the ISE. A potential develops across the membrane that depends on the difference in the activity of a specific ion on each side of the membrane. An internal solution with a fixed ...

Chloride and Salinity - Lamont–Doherty Earth Observatory
www.ldeo.columbia.eduA Vernier Chloride Ion-Selective Electrode is used to measure the chloride ion concentration in the water (in mg/L) either on site or after returning to the lab. Salinity can be determined using the relationship, salinity (ppt) = 0.0018066 5 Cl– (mg/L). Method 2: Salinity Using a Conductivity Probe (Seawater or Brackish Water)
