Extraction of metal cation through liquid membrane is one of the important application of supramolecular chemistry. This work investigates the use of synthetic carrier (ionophore) for the extraction of transition metal cations. In this work effect of light on extraction of metal cations through chromophoricionophore have been tested. For this purpose, a non-cyclic ionophore,1-phenylazonaphth-2-olhas been used to extract transition metal cations (Co²⁺, Ni²⁺, Cu²⁺ and Zn²⁺). Chloroform is used as a solvent. The extracted amount of metal cations depends mainly upon the structure and the concentration of the ionophoreand also on the concentration of metal ions. These studies were focused on the capacity of the ionophore to extract metal cation from an aqueous phase into an Organic phase by complexation.On comparing the results of extraction of metal cations (Co²⁺, Ni²⁺, Cu²⁺ and Zn²⁺) with ionophores1-phenylazonaphth-2-olin the presence of artificial light source (100W) and natural light it is observed that these ionophores exhibit the photo responsive properties.
