Preconcentration of Zn(II) Using β-CyclodextrinButanediolDiglycidyl Ether Polymer Modified With 1-(2-Pyridylazo)-2-Naphthol) (PAN)

In this study, a solid phase extraction method has been developed for the preconcentration of Zninsert ignore into journalissuearticles values(II); at trace level using β-cyclodextrin polymer modified with 1-insert ignore into journalissuearticles values(2-Pyridylazo);-2-Naphthol insert ignore into journalissuearticles values(PAN); reagent. After preconcentration, metal retained on the polymer was eluted with 5.0 mL of 2.0M HCl and then determined by UV-VIS spectrophotometry. The factors affecting the preconcentration of the Zninsert ignore into journalissuearticles values(II); such as pH, concentration of the eluent, eluent volume and matrix components were also ascertained. The recovery of Zninsert ignore into journalissuearticles values(II); was found to be ≥ 95% and preconcentration factor was found to be 70. The relative standard deviation of the method was 1.0%. The analytical detection limit was found to be 2.06 ng/mL.The proposed method has been applied for the determination of Zninsert ignore into journalissuearticles values(II); in different water samples and certified alloy samples.   Keywords: β-cyclodextrin polymer, Zninsert ignore into journalissuearticles values(II);, preconcentration, 1-insert ignore into journalissuearticles values(2-Pyridylazo);-2-Naphthol
