摘　　要：为减小试验误差,优化了粘胶中含硫量的测试方法。探讨了双氧水加入量、自然氧化时间、煮沸时间等因素的影响。结果表明,测试最佳条件为:双氧水加入量10 mL、自然氧化时间10 min、煮沸时间5 min。同一批次样品测试10次结果显示:粘胶中的含硫量最大值为2.310%、最小值为2.296%、平均值为2.300%、RSD值为0.18%。此方法适用于粘胶纤维生产企业在粘胶生产过程中对含硫量的测试。In order to reduce the measuring error, the testing method of sulfur content in viscose is optimized. Factors including hydrogen peroxide amount, natural oxidation time, boiling time are also investigated. The experimental results show that the optimum conditions are hydrogen peroxide 10 mL, natural oxidation for 10 min, and boiling for 5 min. The results of 10 parallel testing show that the maximum, minimum, average value and RSD are 2.310%, 2.296%, 2.300% and 0. 18% respectively. This method is suitable for detection of sulfur content in viscose production.
