动力学光度法测定痕量铂的研究
Determination of Trace Platinum by Kinetic-Spectrophotometry
【摘要】 本文研究了氨水介质中,痕量铂(Ⅳ)阻抑过氧化氢氧化二甲苯蓝FF褪色的新指示反应及其动力学条件,建立了动力学光度法测定痕量铂(Ⅳ)的新方法。方法灵敏度为2.6×10-11g Pt(Ⅳ)/ml,测定范围为0~1.0μg Pt(Ⅳ)/ml。
【Abstract】 Trace platinum (Ⅳ) in aqueous ammonia inhibits a new descoloring reaction of oxidizing xylene blue FF with hydrogen peroxide. Thus a spectrophotometric method for the determination of trace Pt(Ⅳ) has been proposed. The sensitivity of the method is 2. 6 × 10 -11 g/ml for Pt(Ⅳ). The range of the determination of Pt(Ⅳ) is 0-1. 0μg/25 ml.
