HNS recovery from DMF recrystallization filtrate. Progress report, July--September 1975

Description: A recrystallization process was developed and documented, whereby 2,2', 4,4', 6,6'-hexanitrostilbene (HNS), with an approximate bulk density of 0.5 g/cc, can be reproducibly obtained from solution in N,N-dimethyl formamide (DMF). During the process, however, a portion of the solute is tenaciously retained by the filtrate. The high-cost of HNS warrants its extraction; consequently a low-cost recovery method was pursued. Low-cost recovery of HNS, retained by the filtrate during the recrystallizat… more

Removal of Plutonium From Drinking Water by Community Water Treatment Facilities

Description: Plutonium removal factors (RF) averaged 14 +- 10 during a study of the effectiveness of three drinking-water treatment plants for removing Pu from Savannah River water. Plutonium concentrations between 0.1 and 3.5 femtocurie/l were measured in raw and finished water samples. From 50 to 10,000 liter samples of water were concentrated by ion exchange techniques and processed to determine the concentrations of $sup 239$Pu and $sup 240$Pu and to derive Pu RF's. The similarity between RF's observed … more
