| 摘 要： | 本文阐述了用交流示波极谱滴定法测定高钙镁铅锌矿中的锌。在NH_4Cl—NH_3H_2O(pH=10)支持电解质中采用微银汞膜电极进行实验。分别用NH_4F和铜试剂掩蔽钙、镁、铜、铅、镉及其它竽金属元素。铁和铝不干扰测定。用EDTA滴定锌获得令人满意的结果,对两种矿样分析,准标偏差为0.05%和0.07%。该法快速准确,适用于测定高钙镁的铅锌矿中锌。

| Abstract: | Zinc in ores was determined by oscillopolarographic EDTA titration, with mercury film mi-cro-silver electrode, using NH_4Cl-NH_3H_2O(pH=10)as supporting electrolyte, NH-4 and sodiumdiethyldithiocarbamate as masking reagents to eliminate the interferences of Ca, Mg, Cu, Pb-and other heavy metal in the ore. Satisfactory results were obtained with standard devitionranging 0.05 to 0.07% by the method. |
