摘要
把荧光素固定在经处理的生物膜上，研制成光导纤维生物膜碘荧光传感器。Ｉ－的线性响应范围为３×１０－５ｍｏｌ／Ｌ—５×１０－３ｍｏｌ／Ｌ，相对标准偏差为０６５％，响应时间为２５～３５ｍｉｎ。
A new type of fiber optical sensor based on the use of bio membrane is proposed for the determination of iodide Fluorescein is immobilized on bio membrane amd attached to the fiber optic Fluorescense respone is linear between 3×10 -5 mol/L 5×10 -3 mol/L,the relative standard error is 0 65%,the respone time is 2 5～3 5min
