Valorization of BaCO 3 with 8-HQS to produce the optical chemo-probe for highly selective sensing of Cd 2+ in aqueous media

Key Points

• The aim is to utilize barium carbonate and 8-HQS to create a chemo-probe for detecting cadmium ions in water.
• Valorization of BaCO3 with 8-HQS to form an optical chemo-probe.
• Assessment of the probe's selectivity and sensitivity towards Cd2+ in aqueous solutions.
• The chemo-probe shows highly selective sensing for Cd2+ in aqueous media.
• Enhanced sensitivity is achieved in comparison to traditional methods.
