| Abstract: | The polarographic behaviour of 2-benzilideniminobenzohydroxamic acid (2-BIBH) solutions and of 2-BIBH solutions in the presence of Mo(VI) have been studied by using differential pulse polarography and cyclic voltammetry. The polarographic characteristics of the resulting waves have been studied and possible mechanisms of the processes involved have been proposed. A linear relationship has been observed betweenI
p and Mo(VI) concentration in the range 2×10–6 to 1.6×10–5

M 2-BIBH. Standard deviations of 5.6×10–8 and 1.2×10–8
M were found for 3×10–6 and 8 × 10–6
