| ABSTRACT
|
Coated wire lithium ion selective electrode was fabricated using lithium ionophore- VI, 2-nitrophenyl octyl ether (NPOE) and potassium tetrakistp-chlorophenyllborate (KTpCIPB) on platinum wire. Lithium ion selective electrode was giving Nernstian response from 10-1M to 1O-4IM with a detection limit of3xl0-5M. The calibration slope ofthis lithium ion selective electrode was found to be 58.5 ± 1.0 mVldecade. The selectivity coefficients of this electrode with respect to the different ions "'ere determined by matched potential method. This lithium ion selective electrode was then used for the determination of lithium in complex chemical matrix containing hexamethylene tetramine, formaldehyde, urea and ammonium nitrate etc. which are the wash streams generated during the sol-gel process employedfor preparation ofLi2Ti03 microspheres. |
