用测定铜离子浓度鉴别铜氨与莱赛尔纤维初探

本文通过分析铜氨、莱赛尔两种纤维不同的生产工艺，尝试采用火焰原子吸收分光光度法分别测定这两种纤维的铜离子含量，通过分析鉴别铜氨与莱赛尔纤维。结果表明铜氨与莱赛尔两种纤维的铜离子浓度区域有较大的差别，证明这种方法可作为鉴别这两种纤维的辅助方法。

Discussion on the Detection of Cupro Fiber and Lyocell Fiber by Measuring the Concentration of Cu~(2+)

This paper tries to detect Cupro fiber and Lyocell fiber by measuring the concentration of Cu2+ using the method of Flame Atomic Absorption Spectrophotometry through analyzing the different manufacturing techniques of the two kinds of fibers.The result shows that the concentration of Cu2+ of the two fibers differs from each other greatly,which proves that this method can be used as a assisting methods in detecting the two kinds of fibers.
