We present a study of the performance of capacitive deionization (CDI) when applied to electrosorption in an organic solvent, finding enhanced cell charging voltages and improved salt sorption over electrosoprtion in aqueous solutions.

Electrical Double Layers

The capacitive deionization (CDI) method, in which the capacitance of the electrical double layers is used for removing ions from aqueous solutions, can be more efficient if some procedures are devised to help the bare electrode double layers in adsorbing ions.

SummaryUranium, plutonium and fission products are separated by means of a simple multistage extraction of 20% TBP-carbontetrachloride vs. nitric acid series. In order to enhance the mutual separation, the acidity of the aqueous portions is lowered stepwise. All fission products, plutonium and uranium are obtained in aqueous solutions in the sequence mentioned, leaving no active material in the organic solutions of the extractor. The plutonium fractions contain some fission products and a small amount of uranium. However, uranium is obtained with a fairly high purity. The same organic solutions can be used several times giving more or less the same separated products.

Cells of the green alga, Apjohnia laeterivens Harvey, have been ruptured in a Waring blendor in order to remove the majority of the protoplast from the cell-wall substances. The cell walls have been shown to contain, apart from extraneous protoplasmic constituents and some encrusting bryozoa, framework microfibrils of cellulose 1 which seem to be associated with pectin-like materials, arabinogalactan matrix substances and, perhaps, a polysaccharide-protein complex; these components appear to represent about 90% of the organic substances in the original organic-solvent extracted cell walls. Less than 25 % of the initial cellulose 1 was converted to cellulose 11 during treatments of several hours' duration at room temperature with aqueous solutions of 24% KOH and 17.5 % NaOH. The low degree of conversion is attributed to the presence of highly ordered and/or large "crystalline" aggregates of �-1,4'-glucan molecules in the cellulosic micelles of the framework microfibrils of the cell walls.
