A direct method to determine the adsorbed dyes on adsorbent via processing of diffuse reflectance spectroscopy data

In this communication, we have put forward diffuse reflectance spectroscopy (DRS; measured from ultraviolet to near-infrared region) as an efficient tool for the evident confirmation of pollutant dye adsorption on the surface of activated charcoal powder. Typically, Fourier-transform infrared (FTIR) spectroscopy used to validate or differentiate between the pristine and dye-adsorbed adsorbents cum heterogeneous surfaces including photocatalysts that mainly gives information about the functional groups involved in the adsorption process. Here, in addition to the FTIR spectroscopy, DRS in UV-visible region has been endorsed as a potential tool that could be utilized for both to confirm the adsorption and quantification of adsorbate dye present on the adsorbent or heterogeneous surfaces like activated charcoal powder.
