极谱法在地质矿物铜、锌含量测量中的应用

Application of polarography in the measurement of copper and zinc content in geological minerals

极谱法具有操作简单、结果准确等特点,将其应用于地质矿物铜、锌含量测量中,选择某一地质矿物样本作为实验对象,配置完成标准铜、锌溶液后,将其作为标准,乙二胺四乙酸(EDTA)做掩蔽剂,在盐酸-氯化铵底液中,使用JP-2D型极谱分析仪,于峰电位-480mV(相对于饱和甘汞电极)测定铜、锌。分析实验结果可以看出,极谱法能够较好满足地质矿物测量需求。

Polarography has the characteristics of simple operation and accurate results.A geological mineral sample is selected as the experimental object.After the preparation of standard copper and zinc solution,the standard copper and zinc solution is used as the standard,and EDTA is used as the masking agent.The jp-2d polarographic analyzer is used in the hydrochloric acid ammonium chloride bottom solution,Copper and zinc were determined at-480 MV(relative to saturated calomel electrode).Analysis of the experimental results show that polarography can better meet the needs of geological and mineral measurement.
