把荧光素固定在经处理的生物膜(新鲜羊肉膜)上,研制成光导纤维生物膜溴传感器。用该传感器对工业废水中的溴化物进行了监测。荧光线性响应范围8×10-7~2×10-5mol/L,相对标准偏差0.8%,响应时间2~3min。
Fluorescein was immobilized on a treated biofilm (fresh lamb membrane) and developed into a fiber optic biofilm bromine sensor. The sensor was used to monitor bromide in industrial wastewater. Fluorescence linear response range of 8 × 10-7 ~ 2 × 10-5mol / L, the relative standard deviation of 0.8%, the response time of 2 ~ 3min.
