Clotrimazole-triiodide ion association as an ion exchanger for a triiodide ion-selective electrode.
A novel triiodide ion-selective electrode based on a clotrimazole-triiodide ion pair as a membrane carrier was prepared. It has a linear response to triiodide from 8 x 10(-6) to 5 x 10(-3) M with a slope of -68.9 mV per decade and a detection limit of 5 x 10(-6) M. The electrode response is independent of the pH of the solution in the pH range 2-9. It has a very short response time and can be u...

A highly selective electrode for Bromide ion based on aza pyrilium derivative as an excellentionophore is described.The sensor exhibits a good linear response with a slope of ( 60±1 ) mV per decadeover the concentration range of ( 1×10-3 – 9×10-6 M ) , and a detection limit of ( 3×10-6 M ) of Bromideions .The electrode response is independent of pH in the range of(4.0 –9.5).Selectivity coeffici...
متن کاملXAFS analysis of triiodide ion in solutions.
Iodine K-edge XAFS of triiodide ions in various solvents were measured at SPring-8 BL01B1 and analyzed. Though the anion takes a linear and symmetric form, the second peak expected from enhanced multiple scatterings can be hardly observed because of its large vibrations. The bond distances and the Debye-Waller factors for the I-I couple vary when protic solvents were used and they were similar ...
متن کاملCharge-transfer triiodide ion-selective electrode based on 7,16-dibenzyl-1,4,10,13-tetraoxa-7,16-diazacyclooctadecane.
A new PVC membrane electrode for the triiodide ion based on a charge-transfer complex of iodine with 7,16-dibenzyl-1,4,10,13-tetraoxa-7,16-diazacyclooctadecane as a membrane carrier was prepared. The electrode exhibits a Nernstian response for triiodide ions over a wide concentration range (1.0 x 10(-1)-1.0 x 10(-5) M) with a slope of 59.3 +/- 0.9 mV decade(-1) and a detection limit of 6.3 x 10...
