摘要
基于在稀氨水介质中 ,痕量铁可催化过氧化氢氧化碱性品红褪色的反应 ,建立了一种动力学光度法测定高纯碳酸锂中痕量铁的新方法 ,该方法线性范围为 0 - 2ug/ 2 5mL ,检出限为 1.8×10 - 10 g/mL。用于高纯碳酸锂中痕量铁的测定 。
A new kinetic-spectrophotometric method for the determination of traec Fe in pure Lithium carbonate was developed. It is based on the inhibition of the Fe catalysed discoloring reaction of Fuchsin basic oxidized by H 2O 2 in ammonium hydroxide medium.The linear range of determination is 0-2ug/mL, and detection limit is 1.8×10 -10 g/mL. The method was used for the determination of trace Fe in lithium carbonate with satisfactory results.
