Bis-thiosemicarbazone functions as a selective chemosensor with the lowest LOD for Hg ions in water-rich medium: implications for on-site detection and logic gate experiments

Key Points

• This research aims to explore the application of a bis-thiosemicarbazone as a selective chemosensor for mercury ions in water.
• Utilized a mesitylene-anchored bis-thiosemicarbazone (TOMH) as a chemosensor.
• Tested the chemosensor for selective detection among various metal ions in an aqueous medium.
• Achieved the lowest limit of detection (LOD) for mercury ions compared to other metal ions.
• Demonstrated effective function of TOMH in water-rich environments.
