Abstract
Coated wire lithium ion selective electrode was fabricated using lithium ionophore-VI, 2-nitrophenyl octyl ether
(NPOE) and potassium tetrakis(p-chlorophenyl)borate (KTpClPB) on platinum wire. Lithium ion selective
electrode was giving Nernstian response from 10-1M to 10-4M with a detection limit of 3x10-5M. The calibration
slope of this lithium ion selective electrode was found to be 58.5 ± 1.0 mV/decade. The selectivity coefficients of
this electrode with respect to the different ions were 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 employed for preparation of Li2TiO3 microspheres.
