Abstract :This paper presents a chelating agent free solid phase extraction insert ignore into journalissuearticles values(CAF-SPE); method for the separation and/or preconcentration of trace ironinsert ignore into journalissuearticles values(III); ions. This method is based on the sorption of Feinsert ignore into journalissuearticles values(III); ions without using any chelating agent onto Amberlyst 36 resin. A good relative standard deviation insert ignore into journalissuearticles values(3%);, high recovery insert ignore into journalissuearticles values(>95%);, high enrichment factor insert ignore into journalissuearticles values(100);, and low detection limit insert ignore into journalissuearticles values(0.32 m g L-1); were obtained. The adsorption capacity of resin was 117 mg g-1 for ironinsert ignore into journalissuearticles values(III);. The method was applied for the determination of iron various in water and commercial tea bag samples. The accuracy of the method was confirmed by analyzing Certified Reference Material insert ignore into journalissuearticles values(GBW 07605);.
