Use of methyltrioctyl/decylammonium bis 2,4,4-(trimethylpentyl)phosphinate ionic liquid (ALiCY IL) on the boron extraction in chloride media

► Three ILs extractants have been synthesised for the separation and recovery of boron. ► The low solubility of these ILs overcome the stability problems of SLM processes. ► Boron extracted can be easily stripped with a 0.2 M NaOH/ 0.3 M NaCl solution. ► The Ils designed have shown a promising behavior with FSSLM.
