| 摘 要： | 利用皂石的反射紫外线作用,在表面活性剂的作用下将亚甲蓝、抗坏血酸引入皂石的层间结构中,从而制成一种新型的氧气指示剂并解决了亚甲蓝易于被光降解的问题,克服了其它变色型氧气指示剂需要避光保存的问题。该氧气指示剂在氧气含量小于0.1%时为红色,当氧气含量上升到0.5%时迅速变为蓝色,具有较灵敏的检测氧气的功能。并且探讨了表面活性剂在氧气指示剂中的作用。

| Abstract: | A new intercalated oxygen indicator consisting of methylene blue,a cationic surfactant,ascorbic acid and saponite was made to serve as oxygen indicator.This oxygen indicator has better ability of anti-photofading and overcome the problem which keeps in the dark.It exhibited red color at oxygen concentrations of less than 0.1 % and rapidly turned blue color while oxygen content reached 0.5 %.The oxygen indicator has a good performance of indicating oxygen.The function of surfactant was investigated primarily in the paper. |

| Keywords: | modified atmosphere package oxygen indicator anti-photofading methylene blue saponite surfactant |
