Abstract:
Same quantities of ciprofloxacin (0.2, 0.4, 0.6, 0.8 and 1.00 µg/liter) were determined by using atomic absorption Spectrophotometric (AAS) and high pressure liquid chromatography (HPLC) techniques. AAS technique was introduced as the test method where HPLC method was applied as the reference method as to validate the results of test method. In HPLC method reverse phase C18 column (RPC18 column) was used where mixture of acetonitrile: Phosphate buffer (35:65) was employed as mobile phase. In AAS method 284 nm wavelength revealed the maximum absorption and therefore further all the measurements were recorded using this wavelength. In AAS test technique, at ifrst step ciprofloxacin was fused with sodium biphenyl. Then sodium fluoride (NaF) formed was reacted with FeCl3 to give iron fluoride (FeF3). The extra amount of FeCl3 was removed by reacting it with ammonium thiocyanate. Ferric thiocyanate (FeSCN) was selectively dissolved in Methyl Isobutyl Ketone (MIBK) and separated by filtration. NH4Cl and ferric thiocyanate were held back. Amount of Fluorine (F) was determined in terms of Fe and using this amount, quantity of ciprofloxacin was calculated.
