Differential Pulse Polarographic Determination of Trace Molybdenum in Uranium with α‐Benzoinoxime Extraction

Abstract

A method for the determination of trace molybdenum in uranium is described based on its specific catalytic reduction wave in the presence of nitric acid. Molybdenum is separated from uranium by α‐benzoin oxime extraction and determined by differential pulse polarography. As lower as 1 ng/ml of Mo(VI) is determinable and 98% of recovery can be obtained at present work.

Optimization of Molybdenum Quantitative Separation by Precipitation with a-Benzoine-oxyme Starting from Acidic Solutions

“…The reagent α-benzoine-oxyme (ABO) is used for the quantitative precipitation of some cations, starting from aqueous solutions [4,5]. This analytical reagent is used for the quantitative determination of molybdenum by gravimetric [6][7][8][9], extractive -spectrometric [10], polarographic [11], and flow injection methods [12].…”
