表面活性剂存在下姜黄素与铍铁钛锆的显色反应研究

Study on the Colour Reaction of Curcumin with Be,Fe,Ti and Zr in the Presence of Surfactants

本文研究了姜黄素与一些金属离子的显色反应,探讨了反应机理。结果表明,分别在CPB、TX-100、CPB-TX-100、SDBS存在下,姜黄素可与Be、Fe、Ti、Zr发生灵敏的显色反应。其表观摩尔吸光系数分别为1.25 ×10~5、3.03 ×10~4、6.24×10~4和4.93 ×10~4L·mol^(-1)·cm^(-1)。利用负峰效应提高了Be、Fe两显色体系的灵敏度并测定了络合比。

The dolour reaction of curcumin with metal ions and the mechanism of the reaction Were studied (on the basis of the struotural character of curdu-min, reactive regularity of surfactants and the pinciple of chalate colouring). Sensitivities of the systems of curcumin-Be-CPB and curcumin-Fe-Triton X 100 were improved and the complex ratios determined by using negative peaks.
