Mercury vapor detection using smartphone cameras and red cabbage extract highlighted in Vietnam conference

The detection of mercury vapor or Hg0(g) using Copper(I) Iodide synthesized with red cabbage extract was the highlight of a recent research presentation in Vietnam, where Department of Chemistry Chair and Chemical Sensors researcher Alan Rodelle M. Salcedo, PhD talked about the technique using smartphone camera-based colometric detection. Salcedo, who spoke during the August 25-26, 2023 International Conference on Science, Technology, and Innovation for Sustainable Development in Vietnam, was one of the presenters in the session “Innovative Life Science and Smart Materials.”

Salcedo’s work, based on papers co-authored with Academician Professor Emeritus Fortunato B. Sevilla III, PhD and published in Instrumentation Science and Technology and Acta Manilana, was a response to the need for ways to detect atmospheric pollutants of concern in the environment. Using digital imaging analysis, the parameters included the color values, polymer reagent binder, amount of Cul, exposure time, and Hg0 concentration.

With the theme “Establishment of Sustainable Technological Solution for Industry and Society”, the two-day conference gathered academics, researchers, scholars, and industry practitioners from around the world to share and discuss recent advances in sustainable science, technology, and innovation. The four Innovative Tracks of the conference – Innovative Life Science and Smart Materials (iLS), Innovative Advanced Production and Industrial Engineering (iAP), Innovative Sharing Economy and Sustainable Science (iSE), and Innovative Education Science and Quality Assurance (iES) – guided the discourse, encapsulating a wide array of topics and scopes within the realm of sustainable development.
