A spill of nuclear waste is of an upmost concern for people living near nuclear power plants and potential underground storage caverns. While there a number of techniques that are sensitive enough for the detection of actinides in the environment, they are not portable or cost effective. An UV-Vis spectrometer can be low-cost and portable. Chromophores have been made that will bind actinides selectively resulting in a unique signal; however other metals such as copper can interfere.Previously, our group has synthesized a quinoxaline salen ligand that shows a difference in the UV-Vis between copper and uranyl. Now modifications are being made to increase the detection limit and the changes in the UV-Vis spectra. TDDFT will be used to determine the single electron transitions with NTOs to determine ligand to ligand, ligand to metal, and metal to ligand transitions.
