基于分子发光的新型多孔塑料光纤传感探头的研究(英文)

A new porous plastic optical fiber probe was synthesized and proposed for preparation of optical chemical sensor. The basic principle,fabrication and characteristics of the porous plastic optical fiber probe are described in detail. The polymer fiber was made from the stock mixture of functional monomer,cross linking reagent,pore forming reagent and indicator. And it behaves great advantages as an optical fiber probe. This new porous plastic optical fiber probe has been used for preparing some optical chemical sensors, and these probes have been used for determination of halides, mercury, ammonia, oxygen and pH.

多孔塑料光纤氨传感探头的制备与应用

基于交联共聚技术,以藻红为荧光指示剂,苯乙烯为聚合单体、双甲基丙烯酸一缩二乙二醇酯为交联剂,研制了苯乙烯聚合多孔塑料光纤,用于微量氨的传感分析。研究了荧光指示剂在共聚体中的固定技术,考察了传感探头在不同聚合交联度、惰性致孔剂、荧光指示剂浓度条件下对氨的响应性能的影响。在最优条件下,聚苯乙烯多孔塑料光纤探头透明、刚性、耐水和耐化学性能好,透光率为88%—92%,对氨的检测线性浓度范围为2×10^(-4)—9.1×10^(-3)mol/L,并具有较好的稳定性和可逆性。
