摘要： An electrically regeneratable electrochemical cell (30) for capacitive deionization and electrochemical purification and regeneration of electrodes includes two end plates (31, 32), one at each end of the cell (30). Two end electrodes (35, 36) are arranged one at each end of the cell (30), adjacent to the end plates (31, 32). An insulator layer (33) is interposed between each end plate (31, 32) and the adjacent end electrode (35, 36). Each end electrode (35, 36) includes a single sheet (44) of conductive material having a high specific surface area and sorption capacity. In one embodiment, the sheet (44) of conductive material is formed of carbon aerogel composite. The cell (30) further includes a plurality of generally identical double-sided intermediate electrodes (37-43) that are equidistally separated from each other, between the two end electrodes (35, 36). As the electrolyte enters the cell, it flows through a continuous open serpentine channel (65-71) defined by the electrodes, substantially parallel to the surfaces of the electrodes. By polarizing the cell (30), ions are removed from the electrolyte and are held in the electric double layers formed at the carbon aerogel surfaces of the electrodes. As the cell (30) is saturated with the removed ions, the cell (30) is regenerated electrically, thus significantly minimizing secondary wastes.

摘要： In accordance with the present invention, an improved anion- exchange chromatographic composition has been formed which comprises synthetic resin support particles and anion exchange compounds attached thereto, wherein the anion-exchange compounds comprise an internal reactive group, which may be an ester, ketone or amide group, and a terminal quaternary ammonium salt which functions as an anion-exchange site. The compositions of the present invention exhibit improved hydrolytic stability as compared to other known anion-exchange chromatographic compositions due to the presence of linkers which increase the number of atoms separating the internal reactive group from the nitrogen atom of the terminal ammonium anion-exchange site. Formed articles and methods employing the anion-exchange chromatographic composition are also provided.

摘要： The invention provides a process for detecting the presence of guanidinium ions in a sample solution. The detection process involves contacting a sample solution suspected of containing guanidinium ions with a cation exchange resin and eluting the guanidinium ions present in the sample solution with an aqueous buffer solution having a pH of about 1.5 to about 2. This is followed by contacting the eluant with a cation suppressor column and simultaneously flowing a suppressor regenerate solution in the opposite direction on the opposite side of the permeable membrane of the column, and finally, detecting the presence of guanidinium ions in the eluant from the ion exchange column which was contacted with the suppressor column by use of a conductivity detector.

摘要： A method and apparatus has been provided for generating a high purity aqueous stream with selected ionic species--either cation (e.g. sodium) or anion (e.g. sulfate) and suitable for use as a chromatography eluent. In one form, an eluent generating means defines a source channel and a product channel separated by a permselective ion exchange membrane including exchangeable ions of the same charge as the selected ionic species. The membrane allows passage of ions of the same charge as the ionic species but is resistant to transmembrane passage of ions of opposite charge. Means is provided for applying an electrical potential between the source channel and product channel. In another form of the device, two different membranes define two source channels, a positively charged, anode source channel and a negatively charged cathode source channel, and a product channel. The effluent from the product channel is directed to the chromatographic separation means. Means is also provided for supplying liquid sample to the chromatographic separation means.
