Spectrophotometric Determination of Quinolone Antibiotics by an Association Complex Formation with Aluminum(III) and Erythrosin

Abstract: Ternary complexes can be classified into two major categories: a mixed-ligand complex type and an ion-association complex type. The modes of formation of both types of ternary complex, together with improvements in sensitivity and selectivity which accompany their formation, have been extensively discussed [1][2][3][4][5] in the field of inorganic analysis.In one of the methods to increase the determination sensitivity of organic compounds, the binary ion-pair complex formation between an organic dye and an or… Show more

“…Ofloxacin generates with Al(III) and erythrosin an ion-association complex between {Al III (OFX)} cation and (ERY) anion. The ternary complex has an effective molar absorptivity at 555 nm, allowed spectrophotometrically determination of ofloxacin and other quinolone antibiotics (norfloxacin, enoxacin and levofloxacin) in pharmaceutical preparation [192]. Ion-association complexes formed with [Cr(NCS) 4 (NH 3 ) 2 ] - (Reineckate anion) displaying a maximum absorption at 524 nm were used for determination of ofloxacin [193] and norfloxacin [194].…”

“…The literature revealed many methods for the determination of LEV; including a review on the spectrophotometric methods for its determination up to 2008 [6], other specrophotometric methods [7-9], spectrofluorometric methods [10,11], HPLC with UV detection [12,13], fluorometric detection [14], tandem mass spectrometric detection [15]. Capillary electrophoresis with electrochemiluminescence detection [16], electrochemical methods [17], chemiluminescence [18] and flow injection analysis with UV, potentiometric and conductometric detection [19] were also reported.…”
