Polymer based colorimetric sensor capable of selective detection and separation of copper ions

摘要

The present invention relates to a polymer-based color sensor capable of detecting copper (Cu) and to a method for detecting and / or separating copper using the same, wherein the color sensor includes a repeating unit represented by Chemical Formula 1 and is easy to use in water. , a transition metal (II) ions, especially copper ions (Cu ⁺²⁾ be present in a small amount μM level can be accurately detected with high sensitivity and selectivity. In addition, the color sensor can be turned ON / OFF according to the pH conditions in the water, easy separation of copper ions (Cu ²⁺ ), and can be used as a solid phase such as a film as well as a solution form of high portability Because of the advantages applicable to the product, it can be usefully used in various fields that require the detection and / or separation of copper present in water.
