Introduction The progressively greater number of analytical tests required on a sample and the larger number of samples required for significance of the data demand higher productivity to minimise increases in labour and equipment costs. At the same time, the precision and accuracy of the data must be maintained at the highest possible levels to assure validity of the results. Within the author...

The polarographic study of Cd(II) with L-Tyrosine has been investigated in aqueous organic solvent mixtures at 300K. The Dimethyl sulphoxide and Dimethyl formamide solvents have been used with water to study the effect of solvents on the stability of complexes. Cadmium(II) formed 1:1, 1:2 and 1:3 complexes with L-Tyrosine in the aqueous-organic solvent mixture i.e. DMSO and DMF. The stability c...
