铁氰化钾法测试棉花含糖量的影响因素

Effect factors on determining sugar content of cotton by potassium ferricyanide test method

棉花的含糖量直接影响棉花的质量和纺纱工艺。采用铁氰化钾法测定棉花含糖量,通过分析加热温度、滴定速率、静置时间等因素对棉花含糖量的影响,得到最佳的测定棉花含糖量工艺:加热温度95℃,糖液滴定速率25滴/min,静置时间90 s。

In this paper, effect factors on the determination of sugar content of cotton by using potassium ferricyanide method was studied through analyses of heating temperature, titration rate, holding time and other factors to have an optimized cotton sugar content determination process gotten： heating temperature 95℃, titration rate 25 drops/min, holding time 90 s.
