Abstract

Bromide was separated from highly concentrated brines with selective resins containing Alamine 336. Resins were prepared either by sorbing Alamine 336 on to polymeric adsorbent or by polymerizing monomers in the presence of the extractant. The selectivity of the resins for bromide in brine containing 8.7 M Cl- was in the range of 24-39 compared with 3-6 for conventional resins. The loaded resins were eluted with a base, the chloride being eluted first followed by the bromide; 80% purity was achieved for over 90% of the bromide separated from the "End Brine".
