Abstract: Chemistry Department, Kurukshetra University, Kurukshetra-136 119, Haryana, India E-mail : [email protected] Manuscript received 04 June 2009, revised 26 August 2010. accepted 28 October 2010 A simpIe spectrophotometric method for the trace determination of zirconium is developed using 6-chloro-3- bydroxy-2-[2-(5' -methylfuryi)]-4H-chromen-4-oue (CHMFC) as a complexing agent for the metal ion in acid solution. The resulting complex hears a metal to ligand ratio of 1 : 2 whose absorption maximum lies at 430 mo. The method obeys Beer's law in the range 0-1.5 μg ZrIv ml-1 with a molar absorptivity and Sandell's sensitivity value of 2.32 x 104 L mol-1 cm-1 and 0.0039 μg ZrIv cm-2 respectively. It is also free from the interference of a large number of cations and anions. Utilizing the proposed procedure, the analysis of various synthetic samples und reverberatory flue dust has been carried out to a greater degree of accuracy.
