Abstract:
Dispersive liquid–liquid microextraction coupled with UV–Vis
spectrophotometry was applied for the determination of zirconium
in aqueous samples. In this method a small amount of chloroform as
the extraction solvent was dissolved in pure ethanol as the disperser
solvent, then the binary solution was rapidly injected by a syringe
into the water sample solution containing Zr(IV), xylenol orange and
cetyltrimethylammonium bromide (CTAB). The formed ion-associate
was extracted into the fine chloroform droplets. The detection limit for
Zr(IV) was ۰.۰۱۰ μg mL−۱. The precision of the method, evaluated as
the relative standard deviation obtained by analyzing of ۱۰ replicates,
was ۲.۷ %. The practical applicability of the developed method was
examined using natural waters and ceramic samples.
