Abstract EN
A simple, accurate and sensitive procedure for spectrophotometric determination of yttrium (III) in aqueous solution has been developed.
The method is based on the reaction of yttrium (III) with alizarin red S (ARS) reagent in the presence of cetyltrimethylammonium bromide (CTAB) and triton-X-100 surfactants at pH 4.7 to form a red carmine complex which has maximum absorption at 520 nm.
Beer's law is obeyed over the concentration range 2.5-75 μg yttrium (III) /20 ml, (i.e.
,0.125-3.73 ppm) with a determination coefficient of (0.9954) and molar absorptivity of 1.16×104 l.mol-1.cm-1.
The limit of detection (LOD) and the limit of quantification (LOQ) are 0.1009 and 0.323 μg.mL-1, respectively.
Under optimum conditions, the stoichiometry of the reaction between yttrium (III), alizarin red S and CTAB is found to be 1:2:2, respectively.
The recoveries are obtained in the range of 98.07 - 100.63% and the relative standard deviation is better than ±2.33%.
The method has been successfully applied to the determination of yttrium(III) in natural waters.
