Anodic Stripping Voltrammertic Determination of Trace of Trace Copper in Micro-Sample with a Mercury Unltramicroclectrode

摘要: 研究了在NH₄OH-NH₄Cl介质中,用玻碳电极同位镀汞膜阳级溶出伏安法测定样品中痕量铜,检测限达10^-13 mol/L^-1,可用于多种样品的分析。

Abstract: The Determination of trace copper has been studied by anodic stripping voltammetry with a mercury-plated glassy elecrode in NH₄OH-NH₄Cl supporting elecrolyte solution. The detertion accurate within concentration is 10^-13 mol/L^-1. Various samples can be anamed by this techique.
