The compound 6-amino-5-mercapto-4H-1,2,4-triazol-3-yl)-9-fluoro-3-methyl-10-(4-methylpiperazin-1-yl)-2,3-dihydro-7H-[1,4] oxazino[2,3,4-ij] quinolin-7-one (M1)  synthesize from the reaction of thiocarbohydrazide with levofloxacin acid by using ethanol as a solvent, phenolic Schiff bases (Z)-9-fluoro-6-(4-((4-hydroxybenzylidene) amino)-5-mercapto4H1,2,4-triazol-3-yl)-3-methyl-10-(4-methylpiperazin-1-yl)-2,3-dihydro-7H-[1,4]oxazino[2,3,4-ij] quinolin-7-one (M2), (Z)-6-(4-((2,4-dihydroxybenzylidene) amino)-5-mercapto-4H-1,2,4-triazol-3-yl)-9-fluoro-3-methyl-10-(4-methylpiperazin-1-yl)-2,3-dihydro-7H-[1,4] oxazino[2,3,4-ij]quinolin-7-one (M3) and (Z)-6-(4-((5-chloro-2-hydroxybenzylidene) amino)-5-mercapto-4H-1,2,4-triazol-3-yl)-9-fluoro-3-methyl-10-(4-methylpiperazin-1-yl)-2,3-dihydro-7H- [1,4] oxazino[2,3,4-ij] quinolin-7-one (M4) were prepared from the reaction of trizol derivative of [M1] compound with the appropriate phenolic aldehydes by using ethanol as a solvent. The synthetic Schiff bases used to prepare numbers of phenolic polymers [M5-M7] from the reaction of Schiff bases [M2-M4] with phenol formaldehyde. The analytical efficiency of the synthetic chelating polymers studied by the batch method with different transition metals ions (Cd2+, Fe3+, Cu2+), in terms of the effect of treatment time and the pH on the loading capacity of the polymers, controlling the other factors such as temperature, ions concentration and quantity of polymers. The result shows that the capacity of the polymer increased with increasing of the pH and treating time.  The synthetic compounds were characterized by various instrumental techniques like FTIR, 1H-NMR, DTG and TGA studies.These spectral and thermal studies provide very valuable information about the structural features.
