Cadion 2B-Triton X-100与锌的显色反应及血清中微量锌的分析研究

THE STUDY ON THE COLOUR REACTIONS OF CADION 2B-TRITON X-100 WITH ZINC

本文使用吡啶偶氮类显色剂,对硝基萘重氮氨苯(简称Cadion2B)和微量锌的络合显色反应。该法应用于血清中微量锌的测定,其相对标准偏差小于5％,回收率为95～110％。

The Colour reactions of cadion 2B-Triton X-100 with Zinc was applied to demonstrate Zinc in blood serum.The complex is founed at pH8.5-9.8. The molax absorptivity of the complex is 1.0 ×105L · mol-1·cm-1, Beers law is obeyed over the range of 0-0.48μg/ml, Many metals do not interfere in determination of Zinc. The relative standard deviation was Less 5 %and recoveries were 95-110%.
