Byphenyl hydrazone@SiO₂ composite: shynthesis an evaluation of a new chemosensor system for the detection of Cu²⁺

In the present work a byphenyl hydrazone/SiO₂ composite was synthetized by a simple procedure. First, the mesoporous SiO₂ and the byphenyl hydrazone ligand were prepared. To synthetize the composite, the mesoporous silica and the ligand were dispersed in ethanol/water by a microwave assisted process. The composite was characterized by different techniques to evaluate its properties as chemosensor. The physicochemical characterization of the composite confirmed the selectivity and sensitive capacity to detect Cu⁺² ions.
