“…Several electrometric methods were employed for the determination of selenite in simple solutions or in binary mixtures including polarography with amperometric end point detection [18,191, polarography using the catalytic effect of Se" [20], amperometry [21,22], and potentiometric titrations using a silver-selective electrode [23]. A selenite-responsive electrode was constructed by Malone and Christian [24] based on the use of diaminobenzidene in hexane as a liquid ion exchanger.…”

New electrodes for the selective determination of selenite were constructed by compressing either HgSe03 or a mixture of HgSe03 and Hg2C12. The linear concentration range was 6.0 x 10-5-10-' M with a slope of 29,5mV/concentration decade. The usable pH range for both electrodes was wide (3-10) and their life span was up to 8 days. Selectivity coefficient values were determined for various anions and no significant interferences were observed for most of them. The solubility products of some sparingly soluble selenite salts were determined using the latter electrode.
