Abstrakt: | A new rhodamine-6G hydrazone RHMA has been synthesized using rhodamine-6G hydrazide and 5-Allyl-3-methoxysalicylaldehyde. RHMA has been fully characterized with different spectroscopic methods and single crystal XRD. RHMA can selectively recognize Cu 2+ and Hg 2+ in aqueous media amongst other common competitive metal ions. A significant change in absorbance was observed with Cu 2+ and Hg 2+ ions with emergence of a new peak at λ Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
