A sensitive, simple and selective preconcentration method was developed for the preconcentration of trace amounts of Ni(II) ions using 1-(2-pyridylazo)-2-naphthol (PAN) modified β-cyclodextrin butanediol diglycidyl ether polymer as a solid phase extractant. Potential factors affecting the sorption of Ni(II) were investigated. Meanwhile, the optimum conditions were established. The sorbed Ni(II) was eluted using 5 ml of 2 M HCl. The preconcentrtion factor was 70. The detection limit for Ni(II) was 1.18 ng/ml. The relative standard deviation (RSD %) was >1%. The developed method was successfully applied for the determination of trace Ni(II) in different water and potato chip samples as well as reference alloy samples.
