Cesium Separation. Cesium will be removed from the waste super-nate by sorption on a phenol-sulfonic ion exchange resin such as Duolite (Diamond Shamrock Chemical Co.) ARC 359, as shown in Figure 3. This flowsheet is a modification of one currently being used by ARHCO at Hanford (3), Cesium will be absorbed on the two columns in tandem until breakthrough from the first column exceeds a predetermined level, after which the column will be washed with water (not shown in the diagram) and eluted with a mixture of ammonium carbonate and ammonium hydroxide. Breakthrough will be detected by a gamma ray monitor on the line between the two columns.

Ellis et al. then performed shaker tests similar to Abdul to screen the various solutions. They used 100 g of soil mixed with 200 mL of surfactant solution the mixture was agitated for one hour. Again, both soil and decanted leachate were analyzed. A 1 1 blend of the nonitxiic surfactants Adsee 799 (Witco Chemical Co.) and Hyonic NP-90 (Diamond Shamrock) performed best, removing 93% of the hydrocarbons and 98% of the PCBs. These results were one to two orders of magnitude better than removal with water alone. Optimal concentrations of these surfactants were determined to be 0.75% by volume in further tests.

Vinylidene fluoride (VF2) as well as vinyl fluoride (VF) resemble more ethylene than other vinyl monomers in regard to the properties and can also be polymerized in a manner analogous to that of ethylene. The first successful polymerization of vinylidene fluoride was reported by Du Pont in 1948 [517]. Poly(vinylidene fluoride) (PVF2 or PVDF) is commercially available from various companies (Kureha Chemical Co., Pennalt Chemicals Corp., Solvay Co., Siiddeutsche Kalkstickstoff-Werke AG now Degussa, Diamond Shamrock, Du Pont) since 1965 under the trade names KF, Kynar, Foraflon, Vidar, and Dalvor, respectively. VF2 can be polymerized by free-radical initiators to give high-molar-mass, crystalline polymers.
