A novel Mn(2+) PVC membrane electrode based on a recently synthesized Schiff base.

A new PVC membrane electrode for manganese(II) ion based on a recently synthesized Schiff base of 5-[(4-nitrophenylazo)-N-hexylamine]salicylaldimine is reported. The electrode exhibits a Nernstian response for Mn(2+) ions over a wide concentration range (4.0x10(-7) to 1.
