摘要
讨论了光纤理化检测仪的原理 ,建立了抗坏血酸还原三价铁后 ,以菲咯嗪为显色剂 ,测定水中总铁的新方法。理论和实践证明 ,采用光纤传感检测适应现场检测的要求。
Optical fibers are applied to measuring ferrous ions in water while ferric ions are reduced by ascorbic acid in advance. O-phenanthroline is added to form a complex whose absorbance is correlative to iron ions concentration. The sensor which is developed based on the principle is especially suitable for field testing.
