| 摘 要： | 介绍了一种快速精确测定染色纱线和织物上靛蓝浓度的分光光度法。靛蓝染色纱线被浓硫酸溶解后,对得到的溶液进行分光光度分析。该方法的精确度可用常规的吡啶萃取法进行验证,是一种既快速又安全的方法。

| Abstract: | A rapid, accurate spectrophotometric method of determining the amounts of indigo on dyed yarns and fabrics was presented. The indigo dyed fibre or fabric was dissolved with concentrated sulphuric acid. The solution was analyzed spectrophometrically. The accuracy of this method was comparable with the traditional pyridine extraction procedure. This new method is speedy, accurate and easy to manipulate. |
