3) trace copper(Ⅱ)
痕量铜(Ⅱ)
1.
A new kinetic spectrophotometric method for the determination of trace copper(Ⅱ) is developed based on the catalytic effect of trace copper(Ⅱ) on oxidation of 2 (5 bromo 2 pyridylazo) 5 diethylaminophenoe(5 Br PADAP) with potassium bromate in sulphuric acid solution.
本文基于稀硫酸介质中,痕量铜(Ⅱ)对溴酸钾氧化2-(5-溴-2-吡啶偶氮)-5-二乙氨基酚褪色反应的催化作用,建立了测定痕量铜(Ⅱ)的新型动力学光度法。
