POLAROGRAPHIC-BEHAVIOR OF 2-BENZILIDENIMINOBENZOHYDROXAMIC ACID (2-BIBH) AND 2-BIBH-MO(VI) SYSTEM

The polarographic behaviour of 2-benzilideniminobenzohydroxamic acid ( 2-BIBH) solutions and of 2-BIBH solutions in the presence of Mo(VI) ha ve been studied by using differential pulse polarography and cyclic vo ltammetry. The polarographic characteristics of the resulting waves ha ve been studied and possible mechanisms of the processes involved have been proposed. A linear relationship has been observed between I-p an d Mo(VI) concentration in the range 2 x 10(-6) to 1.6 x 10(-5) M when using 3 x 10(-4) M 2-BIBH. Standard deviations of 5.6 x 10(-8) and 1.2 x 10(-8) M were found for 3 x 10(-6) and 8 x 10(-6) M Mo(VI), respect ively.
