The atomic absorption spectrometry is a traditional analytical method.Flame atomic absorption spectrometry (FAAS), which is frequently used for thedetermination of metal ions because of relatively high sensitivity and selectivity, is lessused for indirect determination of organic species. This thesis has studied the analyticalmethod of determination of levofloxacin, gatifloxacin by flow injection on-line solidphase extraction flame atomic absorption spectrometry. The method has been applied tothe...
