Abstract

This work demonstrates that a silver-embedded zeolite thin film based fiber optic sensor can be used for in situ, real-time monitoring Hg²⁺ in aqueous solution, with high sensitivity and selectivity over competing analytes. The reflection intensity from the zeolite-coated fiber was observed that changes monotonically with the variation of Hg²⁺ concentrations.
