Urinary iodine assays and ionophore based potentiometric iodide sensors.
Urinary Iodine has been widely regarded as a biochemical marker for control of iodine deficiency disorders. Based on the Sandell-Kolthoff reaction, most colorimetric assay methods for urinary iodine (UI) determination that have been developed require pretreatment of urine sample. The non-Sandell-Kolthoff methods for UI assay provide alternative approaches for UI assay requiring only simple pret...
متن کاملA Student-Designed Potentiometric Titration: Quantitative Determination of Iron(II) by Caro's Acid Titration
Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...

متن کاملDetermination of sulfur compounds in hydrotreated transformer base oil by potentiometric titration.
A method was developed to analyze the distribution of sulfur compounds in model sulfur compounds by potentiometric titration, and applied to analyze hydrotreated transformer base oil. Model thioethers were oxidized to corresponding sulfoxides by tetrabutylammonium periodate and sodium metaperiodate, respectively, and the sulfoxides were titrated by perchloric acid titrant in acetic anhydride. T...
متن کاملPotentiometric titration and conformational change in pepsinogen.
Potentiometric titrations of pepsinogen as functions of ionic strength and temperature were studied. It was found that the ionic strength has a minor effect on the titration behavior of the protein. The maximum values of the buffering capacity in the pH range of 6.0 to 9.0 were found at pH values corresponding to those at which a conformational change of the protein occurs as determined by opti...
