离子色谱法测定粘胶纤维残硫量的研究

Study of Residual Sulphur Determination in Rayon Fiber by Ion Cbromatograpby

研究采用氧瓶燃烧和溶解氧化将粘胶纤维中的残硫氧化为可溶性硫酸盐,利用离子色谱法测定粘胶纤维残硫量的分析方法,与重量法相比,该方法具有简便快速,灵敏度高,准确性好的特点,适用于粘胶纤维残硫量的快速分析。

Residual sulfur in rayon fiber is first fired and oxidized in oxygen flask, or is oxidized in sodium hydroxide and hydrogen peroxide solution to generate soluble sulfate salt. Then the sulfate salt is determined by ion chromatography. Compared with gravimetric analysis, this method is simple, sensitive and accurate. Therefore, it is suitable for the fast analysis of residual sulfur in rayon fiber.
