Phytopathology 1976 A Cesium Chloride Flotation ...

2019-4-13  Cesium chloride water solution (1:1, w/v) was found suitable for the separation of microsclerotia from soil particles due to its high specific gravity, low viscosity, and low toxicity toward V. dahliae microsclerotia. Repeated determination of microsclerotia in naturally infested soils at various localities showed high uniformity.

2018-12-16  microsclerotia used. Thus, the cesium chloride flotation technique might enable recovery of 70-80% of the viable microsclerotia. In another experiment, the number of germinating microsclerotia recovered with the cesium chloride flotation technique was compared with that recovered by the wet-sieving technique. A 100% increase in

Purification of Toxoplasma gondii oocysts by cesium ...

2004-3-1  We describe the use of a cesium chloride (CsCl) gradient as an improvement for the purification of Toxoplasma gondii oocysts from concentrated suspensions. After concentration by sucrose flotation, this technique gives a >96% recovery of very pure unsporulated or sporulated oocysts, but requires “fresh” oocysts (≤10 weeks of age).

Selective separation of cesium contaminated clays

2019-1-1  Flotation has been considered for MMTs of varying Cs contamination levels. Cs sorption by MMT was studied across a range Cs + concentrations (0.01–500 mM), with two-site modelling and a range of analytical techniques used to verify the sorption mechanism(s). Flotation in the presence of a collector (ethylhexadecyldimethyl-ammonium-bromide [EDAB]) has been demonstrated with the mechanism for selective separation understood from the physicochemical characterization of MMT

The cesium chloride can therefore be separated from the aluminum oxide (or aluminum and ferric oxides) by water extraction of the converted solids. By thereafter separating the insoluble residue, a purified extract solution of cesium chloride can be obtained. The purified cesium chloride solution can be converted to a solid product by evaporation.
