摘　　要： 以ＡｍｂｅｒｌｙｓｔＡ－２７为载体的光纤铁反射传感器的研究卢建忠，章竹君（南京大学化学系，南京，２１０００８）（陕西师范大学化学系，西安，７１００６２）关键词光纤传感器，反射，铁离子金属离子光纤传感器的设计是基于固定在探头上的指示剂与溶液中金属离子之... A fiber-optic iron reflected sensor has been developed by immobilizing pyrocatecholdisulfonic acid on Amberlyst A-27.The formation of the FeHL complex between iron ion and immobilized pyrocatedisulfonic acid caused a large reflected intensity change at 485 nm,which was due to a sharp change in colour of the reagent phase from white to violet,and iron ion in the solution can be determinated.The sensor has a higher sensitivity as well as good reversibility and has been applied to the determination of water samples. The reaction mechanism was also preliminary studied.
