Abstract

Hg²⁺ is one of the most dangerous pollutants that can cause damage to organs and the immune system. The common detection methods of Hg²⁺ require sophisticated instrumentation and a long time for analysis. The purpose of this study was to develop a sensor for the detection of Hg²⁺ using filter paper immobilized by gold nanoparticles (AuNPs) conjugated with cyanuric acid (CA). The clear color change from pink to bluish purple is the response of the CA-AuNPs filter paper sensor to exposure to Hg²⁺. Detection can be observed visually with the naked eye and/or with imageJ software; the detection limit is 0.05 µM. The colorimetric response of the sensor was also selective towards Hg²⁺ after testing with different metal ions. In addition, the response from the sensor was also consistent for lake water samples spiked with Hg²⁺. The results of this research provide a promising basic technology for the development of sensors that are affordable, fast, portable, and easy to use for the detection and monitoring of Hg²⁺ levels in water.
