Abstract (EN)
11 ABSTRACT In this work, zinc present in environmental samples was complexed with PAR and the complex was adsorbed on anion exchanger Sephadex QAE A-25 and determined directly by solid phase spectrophotometric method. Weather the complex is deteriorate or not was checked by reading the absorbance with 5 minutes intervals. Stochiometry of Zn-PAR complex was investigated both in aqueous phase and solid phase. The detection limits of the complex both in aqueous phase and solid phase were determined and enrichment factor was evaluated. The interference of metal species present in natural waters with Zn-PAR complex was also investigated. Zinc in mineral water as a representative of environmental samples was determined by solid phase spectrophotometric method. KEY WORDS Zinc, PAR, Solid phase spectrophotometry, enrichment, Sephadex, anion exchanger
