In this paper, we studied the precipitation efficiency of five anionic reactive dyes
dissolved in aqueous solution using two selected quaternary salts,
trihexyltetradecylphosphonium chloride (THTDPCl) and Aliquat 336, using
spectroscopic measurements of different molar ratios of the dye to ionic liquid.
Chemical oxygen demand (COD), biochemical oxygen demand (BOD), and
adsorbable organic halogen (AOX) measurements of filtrates from precipitation
were performed. The purpose of this study was to investigate the removal
efficiency of reactive dyes by ionic liquids based on ammonium or phosphonium
quaternary salts. According to the results, neither of the ionic liquids disturbed
BOD measurements, indicating that ionic liquids are not among the biocidal
substances. The results showed that an increase in the molar ratio of the ionic
liquid versus the reactive dye led to a decline in all of the studied parameters.
