САЖЕТАК / ABSTRACT:
This study investigates tetrabutylphosphonium-based ionic liquids for food dye removal via extraction using aqueous biphasic systems with ammonium sulfate. Furthermore, these ionic liquids were used for activated carbon regeneration and employed for dye removal from the water as well. This dual approach achieved high extraction efficiencies (≈ 90%) and nearly complete regeneration (98%) of the activated carbon used as a food dye adsorbent. These findings underscore the potential of tetrabutylphosphonium ionic liquids for managing dye-contaminated water.
