Applications of Ion Selective Electrodes
Enzyme sensor for organophosphorus insecticides organophosphorus hydrolase in a polymer membrane on a pH sensor is used to catalyse the hydrolysis of compounds with phoshate ester functionality. The detected [H+] change is proportional to the concentration of the phosphate ester insecticide. This is a good example of the use of an enzyme to give selectivity to a specific class of compounds. Unf...
متن کاملMechanistic Aspects of Ion-selective Membrane Electrodes. a Subjective View
Progress in the field of ion-selective membrane electrodes is viewed in terms of a dynamic interplay between advances in mechanistic understanding and the development of practical electrodes. Techniques used for the elucidation of glass, liquid, and crystal membrane electrode operation are discussed and possible mechanisms are considered. Scientific progress is limited not only by the rate of g...
متن کاملIon selective electrodes in environmental analysis
An overview is given dealing with the application of ion-selective electrodes (ISEs) in environmental analysis. ISEs are placed into the context of the trend of development of sensors for extensive and frequent monitoring. Discussed are the issues such as sensing platforms and their mass-production, improvement of precision, diagnostic of sensor functionality, and development of reference elect...
متن کاملWorking mechanism of ion-selective electrodes
A theory for the interpretation of the operation mechanism of ion-selective membrane electrodes is briefly outlined. The statements are based on the accumulated results concerning the electrochemical and spectrochemical behaviour of ion-selective membranes.
متن کاملDetermination of sodium with ion-selective electrodes.
The advent of ion-selective electrodes made possible the potentiometry of sodium in serum and plasma. These methods were based on dilution of serum, as done in flame photometry, and the results were identical. Analysis of whole blood precludes dilution and so "direct" potentiometry was developed. Results by this technique are variable but tend to compensate for the spurious hyponatremias found ...
