  triiodide ion
PVC-based Cu (II)-Schiff base complex membrane coated graphite electrode for the determination of the triiodide ion
      
The electrode was used as an indicator electrode in the potentiometric titration of the triiodide ion and in the determination of ascorbic acid in vitamin C tablets.
      
The electrode shows a Nernstian behavior (slope of 58.2 ± 0.3) over a very wide triiodide ion concentration range (5.0 × 10-8-1.0 × 10-2 M), and has a low detection limit (4.0 × 10-8 M).
      
In fact, the selectivity behavior of the proposed triiodide ion-selective electrode shows great improvements compared to the previously reported electrodes for triiodide ion.
      
The deceleration of the transport processes in solutions containing glycerol is shown to be due to a considerable decrease in the triiodide ion diffusion coefficient.

According to the ultraviolet absorption spectra of iodine,iodide ion and triiodide ion, a method for determination of iodine in edible salt added potassium iodate was proposed. In the medium of HCl with pH 2.4, 0.01?mol/L KI, 1 mol potassium iodate may be quantitatively converted into 3?mol I 3-.By measuring the absorbance of I 3- at 288 or 350 nm, quantity of iodine in edible salt can be calculated. A recovery percent of this method was found to be 96.8?%~102.6?%. Two samples of edible salt purchased from...
