Abstract
Department of Chemistry, M. L. Sukhadia University, Udaipur-313 00 I, India E-mail : akumargoswami@rediffmail.com Manuscript received 8 April 2002, revised II February 2003, accepted 4 March 2003 p-Sulfonamidophenylazobisacetoxime has been used for spectrophotometric determination of iron(III) at 405 nm, keeping the pH at 2.5-3.0. Beer's law is obeyed in the range (4 to 24) x 10-5 M. The molar absorptivity and Sandell's sensitivity values are 1853 dm3 mol-1 cm-1 and 30.14 ng cm-2, respectively.
