Construction and Study of New Ion Selective Electrodes for the Determination Promethazine Hydrochloride and Indium (III)
Ion selective electrodes (ISEs) are part of group of relatively simple and inexpensive analytical tools which are commonly referred to as sensors. The pH electrode is the most well known and simplest member of this group and can be used to illustrate the basic principles of ion selective electrodes [1]. Also, ISE is a transducer sensor which converts the activity of a specific ion dissolved in
