Description
Summary:We introduce the concept of water-soluble natural dye (betanin) as a novel colorimetric sensor for the naked eye detection of copper ions in water samples. Such simple, green, fast, selective and low-cost colorimetric determination of Cu 2+ ions would definitely enhance the environmental and economic benefits of this alternative form of synthetic chelating agent. A betanin-based colorimetric probe was simply extracted from bougainvillea flowers for the selective detection of Cu 2+ ions. The experimental results showed that the betanin pigment could be employed as an optical sensor for Cu 2+ with significant color changes in tap water samples.
