Abstract (300 words maximum)
Textile dyes are known to become harmful and hurt aquatic life. Within day to day and common use this can be mainly found within countries with more manufacturing textiles and food packaging. Developing countries like China, India and Vietnam are some of the places that have a strong hold on the textile industry. When these dyes are no longer of use or deemed out of date in some of these other countries often these are improperly disposed of into lakes and rivers, that can increase pollution and weaken water quality. Deep Eutectic Solvents (DESs) are a potential green sustainability solvent that contains a hydrogen donor and acceptor. The overall purpose of this study was to synthesis various types of Deep Eutectic Solvents and to test their performance on removing dyes. Menthol:Thymol, Camphor:Thymol, Camphor:Menthol and Methnol:Octanoic Acid DESs were prepared with 1:1 ratio by heating at 50-80 °C and stirring at 600 rpm. The synthesis of DESs were confirmed by ATR-FTIR spectroscopy. A model dye, methyl orange, was used in this study. A calibration curve was developed using LCMS and various concentrations of methyl orange. To assess the dye removal efficiency, DES was mixed with dye, stirred for about an hour then centrifuged and analyzed by LCMS. Preliminary results showed that some DESs can moderately remove the dye from water.
