A surface plasmon resonance (SPR) optical fiber sensor for detection of Pb2+ ions. The sensor is based on a modified fiber optic surface with Pb2+-selective recognition elements. No food matrix samples were analysed; the paper reports method development and characterisation of LOD, selectivity, and sensitivity parameters.
Key numbers
- Specific LOD, linear range, and selectivity data not extracted (paper classified at abstract level; full tables in paper).
- No occurrence data for Pb in food or food-grade matrices.
Methods (brief)
SPR-based optical fiber sensing. Measures total aqueous Pb2+. No speciation. No food occurrence data.
Implications
Certification: Method development only; no food concentration data. Courses: Demonstrates optical-fiber-based SPR as an alternative detection approach for Pb.
