Abstract:
Nowadays consciousness on metal pollution increases, heavy metal pollution reduction strategies became major field of interest. In literature many organic reagents were used to determine heavy metals and their stability studies were done. Apart from potentiometry, polarography is one of the best electro analytical technique to study the stability of metal complexes, In this present investigation author studied stability of Cd(II) in presence of 2-(3,4-dimethoxy Benzylideneamino)-2-methyl propane-1-ol by dc polarography. Colourless 2-(3, 4-dimethoxy Benzylideneamino)-2-methyl propane-1-ol (B.P.1030C) is prepared by condensation of 2-amino-2-methyl-1-propanol and 3, 4 dimethoxy benzaldehyde and purified. Characterized by IR, UV and Elemental analyzer. Current-voltage curves of2-(3, 4-Dimethoxy Benzylidene Amino)-2-methyl propane-1-ol and Cadmium (II) recorded separately by using An ELICO DC recording polarograph model CL-357 (Digital). Saturated calomel electrode (SCE) was used as reference electrode. An ELICO glass capillary having the following characteristics m = 1.7434 mg sec-1, t = 4.00 sec at constant height of mercury head 67.0 cm (in 0.1M KNO3 in open circuit) was used. Effect of hydrogen ion concentration, Effect of Ligand concentration, Effect of height of mercury column on polarograms of azomethine was studied. Millicoulometric method is employed in order to calculate electron donating probability of new azo methine. After this polarographic behavior of Cd (II) in presence of new azomethine studied in 40%v/v methanol-water system. Deford-Hume method employed to evaluate consecutive stability constants [Fo] [F1] [F2] [F3] [F4] and metal to ligand ratio of metal with organic reagent. From this studies it was observed that Cd(II) complex showed irreversible two electron reduction and 1:4 metal to ligand ratio with consecutive stability constants as β1 = 0.90 x 102-, β2 = 5.0 x 103-, β3 = 2.30 x10 5-, β4 = 4.0 x 106-.
