Tetrabutylammonium fluoride (TBAF) is a commonly used fluoride source. However, in high concentrations commercial TBAF often possesses a visible, pale yellow impurity. While the yellow color is acknowledged by commercial suppliers, the effect of the impurity in UV/vis and fluorescence spectroscopy has not been documented. Through this research, the effect of this impurity on the UV/vis and fluorescence spectrums of several TBAF samples was studied. The identification and removal of the impurity was an additional focus of the research.
