汞微电极阳极溶出伏安法测定痕量铜
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10-13mol/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 10-13mol/L-1. Various samples can be anamed by this techique.
