✦ Synopsis

The differential pulse olarography technique (DPP) has been utilized to study the behaviour of indole-2hydroxamic acid (2-IHA). %is is a novel hydroxamic acid synthesized for us which exhibits properties as a ligand of metallic species. This Ii and may enhance the determination of many trace metals using analytical techniques such as HPLC and D%P but first the roperties of this li and were studied. This reagent gives rise to one cathodic wave with an Ep value of -0, ! 6 V. versus A /A %I at pH 0.92. The principal characteristics of this wave have been stu8ief and the possible mechanisms for the electrode process proposed.

Under optimum conditions the limit of detection is ~x I O -~ M.
