本文论述了在大量氧化锌、硫化锌存在下,金属锌的分相测定问题。在乙酸铵溶液中,运用阳离子表面活性剂溴化十六烷基三甲铵与少量硫酸亚铁在金属锌表面形成薄膜抑制金属锌溶解,可以分相测定金属锌。在此基础上,建立了锌物相分析流程。 This article discusses the determination of the phase separation of metallic zinc in the presence of a large amount of zinc oxide and zinc sulfide. In ammonium acetate solution, a cationic surfactant, cetyltrimethylammonium bromide and a small amount of ferrous sulfate were used to form a film on the surface of zinc metal to suppress the dissolution of metal zinc. On this basis, established a zinc phase analysis process.
