In this study, a highly sensitive optical probe is designed, fabricated, and evaluated that is composed of a microfluidic device integrated with a fiber optic sensor for environmental monitoring. The resonant cavity is coated with a metal ion‐responsive molecularly imprinted nanocomposite film and monitored by a single‐mode fiber (SMF) optic sensor. The resulting Fabry–Pérot cavity‐based optical probe can accurately measure Hg levels in water with high sensitivity and stability. The nanocomposite film is synthesized using a one‐pot reaction process involving sodium alginate (SA)‐reduced nanosilver particles (nanoAg) dispersed in polyvinyl alcohol (VA). When an aqueous solution containing mercury is injected into the microfluidic device, interactions between Ag and Hg at the nanoscale form a solid Ag‐Hg solid amalgam in the resonant cavity, and surface plasmon resonance (SPR) and the Fabry–Pérot effect can be exploited to detect the presence of Hg. The synthesis, fabrication, and measurement system of this integrated device is simple and cost effective. The developed sensing heavy metals in wastewater treatment, catalysis enhancement, and nanoscale toxicity assessment, and contributes practically to achieving the sustainable development goal (SDG) of access to safe drinking water.

The natural clinoptilolite zeolite was treated with NaOH and heat. The modified zeolite was then investigated by Field-emission Scanning Electron Microscope (FESEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and BET techniques. The modified zeolite managed to remove mercury ions up to 95%; while raw zeolite showed the maximum Hg removal ability of 35%. Also, the modified zeolite was reused seven times with stable adsorption of mercury ions. Based on the kinetic studies, the adsorption of mercury ion by modified zeolite follows the pseudo-second order model. Moreover, the experimental data were better fitted with Langmuir isothermal model than Freundlich. The removal of toxic mercury ions could serve as a useful solution for today's environmental issues.
