## 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 naphthalene‐methyltrioctylammonium chloride was used as an adsorbent and uranium solution at pH 3.5 with flow rate of 1 mL·min^−1^
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
The separation of uranium VI and lanthanides by capillary elec-Ž . trophoresis CE in the form of anionic complexes with arsenazo III in aqueous background electrolytes was found to depend strongly on the chemistry of the surface of the internal wall capillary. A recently developed separation scheme
