Kinetic, Spectroscopic and Polarographic Determination of Trivalent Ions in an Imine System.

Abstract

Complexes of Al(IlI),  Cr(IlI),  Mn(III),  Fe(III),  Co(III) and Bi(III)
with Schiff's base derived from the condensation of 2-oxo-1-
benzopyran-3-carboxylic acid and o-aminothiophenol have been
prepared.  The kinetic parameters of decomposition have also been
evaluated both by Freeman-Carroll and Sharp-Wentworth methods.
D.C. electrical conductivity of the complexes has been studied.
Differential pulse polarography has been chosen to follow the metal
reduction process.
