We proposed a simple flow-injection spectrophotometric procedure for the determination of yttrium using Arsenazo III and optimized various conditions (pH for color formation and sample, buffer systems, Arsenazo III concentration, injection volume, flow-rate, and mixing coils). The calibration was li

## Abstract A simple and effective method has been presented for the preconcentration of uranium by solid phase extraction. For this purpose arsenazo(III) supported on naphthaleneβmethyltrioctylammonium chloride was used as an adsorbent and uranium solution at pH 3.5 with flow rate of 1 mLΒ·min^β1^
