Sažetak

The formation of greenish yellow coloured complex o.E molybdenum(
VI) with nine new p-substituted cinnamohydroxamic
acids have been studied. This study shows that the molybdenum
complex of nine new hydroxamic acids have molar absorptivities
between 3.5 x 104 and 1.1 x 105 1 moi-1 cm-1• This value is considerably
large as compared to value obtained by benzohydroxamic
acid, N-phenylbenzohydroxamic acid and N-p-chlorophenylbenzo-
hydroxamic acidi.2• A rapid extraction and spectrophotometric
method for the determination of molybdenum is described, employing
the most promising of these reagents, N-p-tolyl-p-methoxycinnamohydroxamic
acid.
