Polarographic study of mixed ligand Trimethylolpropane trithioglycolate-alaninate or aspartate or glutaminate or valinate complexes with cadmium (II) lead (II) and thallium (I), in aqueous non aqueous ethanol
Mixed ligand systems (trimethylolpropanetrithioglycolate -alaninate, trimethylolpro-panetrithioglycolate - aspartate, trimethylolpro-panetrithioglycolate glutaminate, trimethylolpropa- netrithioglycolate valinate, with Cd(II), Pb(ll) and Tl (I) in aqueous-non aqueous (3:1 v/v aqueous ethanol) media at constant ionic strength (KNOj, p = 1.0 M), pH (6.2 ± 0.02) and temperature (303 ± 2K) have been studied polarographica'lly.
Triton X-100 (0.001 %) was used as wave maxima suppressor. It was shown that only one mixed ligand entity (MaixO is formed in case of trimethylolpropanetrithioglycolate alaninate/ aspartate/ glutaminate/ valinate systems (where 'i' is three forCd(ll) and Pb(II), and one for TI(I), j is one for all complexes formed) A and X are trimethylolpropane-trithioglycoiate and alaninate/ aspartate/ glutaminate/ valinate/ respectively. Compositions and stability constants of the single mixed ligand species formed have been evaluated employing Souchay and Faucherr's method.
