AbstractAbstract
[en] Dihexyl N,N-diethylcarbamylmethylenephosphonate (DHDECMP) is an important extractant for partitioning actinides from acidic nuclear waste solutions. A new technique for purifying DHDECMP is presented. Reaction of 20% crude DHDECMP in hexane with 1M mercuric nitrate at 400C precipitates Hg(DHDECMP)NO3. DHDECMP, liberated from the precipitate by treatment with caustic cyanide, is > 95% jpure. The procedue is fast, inexpensive and has a high yield (approx. 85%) compared to previous methods
