摘要：
A simple and sensitive spectrophotometric method for the determination of quinolone antibiotics was established based on an association complex formation with aluminum(III) and erythrosin. In the determination of ofloxacin as a quinolone antibiotic, Beer's law is obeyed in the range of 0.1 - 3.2 mu g ml(-1), with an effective molar absorptivity at 555 nm and the relative standard deviation being 1.2 x 10(5) L mol(-1) cm(-1) and 0.9% (n = 6). This method was Successfully applied to the assay of quinolone antibiotics in pharmaceutical preparations.
