Abstract

In view of the high cost, slow response and insufficient detection limit of traditional detection methods, this paperproposes a high sensitive fiber sensor based on magnetic ion imprinting technology for the detection of lowconcentration of Cd2+. First, the evanescent field and waist cone diameter are analyzed by beam propagation method(BPM), and the sensing unit is prepared. Second, γ-Fe2O3@MAA(M-IIP) magnetic ion printing nanomaterials wereprepared by solid-liquid separation and combined the magnetic blomaterial with the sensing unit by silanlation. Finally, the sensor enables a low-concentration detection of Cd2+. The detection sensitivity was up to 2691.5nm/μMin the rangeof 0-1 μM. The limit of detection (LOD) reached 0.45 nM and the response time was 37s at the lowest concentration. At the same time, the sensor also has good results in terms of structural compactness and production cost.
