Abstract :2-Acetylpyridine-4-phenyl-3-thiosemicarbazone insert ignore into journalissuearticles values(APPT); ligand was incorporated onto Amberlite XAD-2 resin through an azo spacer and characterized by FTIR spectroscopy, elemental analysis, TGA, and SEM analysis. The synthesized resin was used for the preconcentration of Pbinsert ignore into journalissuearticles values(II);, Zninsert ignore into journalissuearticles values(II);, Coinsert ignore into journalissuearticles values(II);, Niinsert ignore into journalissuearticles values(II);, Cuinsert ignore into journalissuearticles values(II);, and Cdinsert ignore into journalissuearticles values(II); ions. The sorbed metal ions were eluted with 10 mL of 2.0 mol L-1 HCl and determined by microsample injection coupled flame atomic spectrometry insert ignore into journalissuearticles values(MIS-FAAS);. The recoveries of studied metal ions were \ge 95.1 % with RSD \ge 4.0 % at optimum pH 8; resin amount, 300 mg; flow rates, 2.0 mL min-1 insert ignore into journalissuearticles values(of eluent); and 3.0 mL min-1 insert ignore into journalissuearticles values(sample solution);. The limits of detection insert ignore into journalissuearticles values(LOD); and limits of quantifications insert ignore into journalissuearticles values(LOQ); of the studied metal ions were 0.11, 0.05, 0.07, 0.08, 0.09, and 0.03; and 0.37, 0.17, 0.21, 0.13, 0.31, and 0.10 m g L-1, respectively, with a preconcentration factor of 500 for the 6 studied metal ions. The total saturation capacity of the resin was 0.36, 1.20, 1.50, 1.61, 1.07, and 0.71 mmol g-1, respectively.
