Chemically modified carbon paste electrode for iodide determination on the basis of cetyltrimethylammonium iodide ion-pair.
A new carbon paste electrode (CPE) for the determination of iodide ion based on a cetyltrimethylammonium iodide (CTMAI) ion pair as an electroactive material is described. The electrode shows a linear response for iodide ion over the concentration range of 4 x 10(-5) M to 1 x 10(-1) M with a lower detection limit of 4 x 10(-5) M at 25 degrees C. The electrode has a Nemstian slope of -55.0 +/- 0...
متن کاملPreparation of a novel iodide-selective electrode based on iodide-miconazole ion-pair and its application to pharmaceutical analysis.
An iodide-miconazole ion-paired complex was used as a suitable ion-exchanger for the preparation of a plasticized-PVC membrane electrode. Among different solvent mediators tested, dioctylsebacate exhibited the proper response characteristics, including Nernstian slope of the calibration curve, fast response time and good reproducibility of the emf values. The electrode exhibits a Nernstian slop...
متن کاملLeaf Abscission Induced by the Iodide Ion.
In the course of biological screening for herbicidal activity in synthetic compounds, various organic iodide complexes had marked defoliating properties when applied to leguminous test plants. Simple iodides such as the salts of alkali metals also caused defoliation. Although this effect has been reported in the patent literature (4, 8), our present investigation was undertaken principally to l...
متن کاملPreconcentration of Trace Vanadium with the Ion Pair of 2-Nitroso-1-Naphthol-4-Sulfonic Acid and Tetradecyldimethylbenzylammonium Chloride Onto Microcrystaline Naphthalene and Determination by Derivative Spectrophotometry
Vanadium is quantitatively retained on 2-nitroso-1-naphhthol-4-sulfonic acid tetradecyldimethlbenzyammonium chloride onto microcrystalline naphthalene in the pH range of 3.0-4.0 from a large volume of aqueous solutions of various alloys and synthetic samples. After filtration, the solid mass consisting of the vanadium complex and naphthalene was dissolved with 5.0 mL of dimethylformamide an...
