Preparation of Low Cost Solid State Silver Sulfide Based Bromide Selective Electrodes

Preparation of Low Cost Solid State Silver Sulfide Based Bromide Selective Electrodes

Preparation and performance of a cost effective silver sulfide based bromide selective membrane is described. A solid contact between membrane and body of the electrode was examined as an ion-selective electrode by determining S 2and Br ions by direct potentiometry. A linear response to bromide ion from 2 x 10 -5 to 10 -1 M with a slope of 57.3 mV per decade [Br ] is observed. The membrane has ...

Polystyrene Based Silver Selective Electrodes

Silver(I) selective sensors have been fabricated from polystyrene matrix membranes containing macrocycle, Me6(14) diene.2HClO4 as ionophore. Best performance was exhibited by the membrane having a composition macrocycle : Polystyrene in the ratio 15:1. This membrane worked well over a wide concentration range 5.0×10–1.0×10M of Ag with a near-Nernstian slope of 53.0 ± 1.0 mV per decade of Ag act...

A Low-Cost Solid State Clothesline Alarm

Modern electrical dryers are often equipped with end-ofcycle alarms, making their use more efficient and reducing the need for periodic monitoring. We believe that lowerincome households as well as ecologically aware consumers, drying their laundry on a clothesline, could benefit from a similar mechanism. Such an alarm must be simple to use, compatible with existing systems and low-cost. This w...

ELECTRODES FOR AQUEOUS ELECTROCHEMICAL CELLS Preparation of Improved, Low-Cost Metal Hydride Electrodes for Automotive Applications

Multi-analyte biochip (MAB) based on all-solid-state ion-selective electrodes (ASSISE) for physiological research.

Lab-on-a-chip (LOC) applications in environmental, biomedical, agricultural, biological, and spaceflight research require an ion-selective electrode (ISE) that can withstand prolonged storage in complex biological media (1-4). An all-solid-state ion-selective-electrode (ASSISE) is especially attractive for the aforementioned applications. The electrode should have the following favorable charac...
