Abstract

Polarographic behaviour of metal ions Lead and Cadmium using Schiff base 2–Hydroxy–5–methoxy Benzaldehyde – Tris [HMBT] Ligand is a new method have not been used so far for the determination of Lead and Cadmium in trace quantities. Effect of pH on wave height for LEAD-[HMBT] cadmium –[HMBT] systems have been studied at pH 5 -8.5 and 7-11 for lead and cadmium respectively in 0.1 m molar NaNo3 and 0.002 % Triton –x–100. Effect of Ligand concentration on lead and cadmium have been studied at PH 8.5 for lead and cadmium, Effect of height of mercury column on LEAD-[HMBT] cadmium –[HMBT] at PH 8.5 , Effect of Lead ion concentration and cadmium ion concentration on the wave height at PH 8.5 have been studied.
