Construction and evaluation of a solid-state iodide selective electrode: A chemical instrumentation laboratory experiment

Method for evaluation of thermal hysteresis characteristics of membrane electrode-reference electrode pairs

“…schutkin reaction is determined to be 1.09 ± 0.03 (for d3). The magnitude of the KIE satisfies the Schowen linear fractionation plot (22) for various types of transmethylations as a typical Sn2 type of reaction (9).…”

Potentiometric measurements in air-segmented streams without debubbling

“…The field of chemically modified electrodes (CMEs) has been the focus of a high level of activity since its inception about 15 years ago (1, 2). Substantial enhancements of the sensitivity, selectivity, or stability of electroanalytical measurements have been achieved by using electrodes modified with an appropriate preconcentrating agent (3-7), by incorporating redox mediators that accelerate electrochemical reaction rates (8-10), or by coating the surface with a permselective film (11,12). Despite the enormous potential of CMEs for chemical analysis, such devices are rarely used for routine quantitative measurements and are not available from commercial sources.…”

“…The cell configuration is shown in Figure 2a. An AgI-Ag2S coprecipitate pellet-sensing membrane was employed, prepared as described elsewhere (11). After construction, the pellet was ground with emery paper to obtain a semicircular shape (Figure 2a).…”

Assembling and Testing a Series of Ion-Selective Electrodes in Analytical Chemistry

“…Many experiments using ISEs have been published in this Journal . − Some use commercial electrodes − ,, to determine Na + , F – , or Ca 2+ . Some use a Ag 2 S pellet , to determine Ag + , Pb 2+ , Cl – , or I – .…”
