摘要
本文研究了在pH =8 8的Na2 B4O7-HCl介质中 ,Bi3+催化H2 O2 氧化苯酚红褪色 ,建立了动力学光度法测定痕量Bi3+的新方法 本法灵繁度高 ,选择性好 ,除Mn2 +、M3+0 等离子外 ,其余共存离子基本无干扰 该法用于测定纯铅中痕量Bi3+。
In this paper bismuth cataly oxidation of phenol red by hydrogen peroxide in the Na 2B 4O 7—HCl butfer (pH=8.8),a new method for catalytic—kinetic spectro—photometric determinativon of trace bismth has been developed.The method is to have higher selectivity and precision.Besides Mn 2+ ,Mo 3+ the other ion don't disturb busically.It has been to determine trace bismuth in pure lead with satis—factory results.
