| 摘 要： | 本文介绍了用系数倍率导数光谱法同时测定黄棕色涤纶上的分散黄ＲＧＦＬ，分散棕２ＲＬ，分散红Ｓ－ＢＷＦＬ的配比。这三种染料吸收峰重叠大，用该法可以完全消除彼此的干扰而不用分离，测得三种染料的配比与工艺配方中的比例一致，结果准确，可靠，回收率较好。这个方法操作简便，快速，可用于纵上染料的测定。

| Abstract: | The determination of Disperse Yellow RGFL, Disperse Brown 2RL and Disperse Red S-BWFL on coloured Dacron fibres by coefficient multiple derivative spectrophotometry is described. Overlapping of the absorption peaks of the three dyes is serious.The mutual interference can be completely eliminated by this method without preliminary separation.The determined ratio of the dye concentrations agreed well with the ratio in the formulation. The method is accurate,reliable,simple,fask and applicable to the determination of dyes on fibres. |
