Determination of chromium by aminohydroxamic acid

الملخص EN

A new histidinehydroxamic acid (HistHA has been synthesized and characterized by IR NMR elemental analysis, as well as reaction to wards acidic solution of vanadium v and iron III to give violet and red colored stable complexes in aqueous layers respectively.

Its analytical properties were investigated, and high affinity and selectivity toward chromium in the presence of large quantities of associated ions.
