摘要： Adsorbed calcium is selectively removed from cation exchange resins in the presence of adsorbed magnesium by eluting the resin with aqueous sulfuric acid saturated with CaSO 4 and undersaturated with MgS0 4 to obtain a solution supersaturated with CaSO 4 from wich the CaSO 4 can be readily precipitated. The magnesium is subsequently removed from the resin by eluting with aqueous sulfuric acid, such as 20-70% H 2 SO 4 . The method is advantageously used in the regeneration of cation exchange resins, such as the loaded resins used for treatment of phosphate rock-derived phosphoric acid.

摘要： Adjustabty metered transfer of res!n increments in folded bad ion exchange systems are provided by a method and apparatus in which compacted liquid-containing resin granules are expelled from a column into a metering chamber which is filled to a level of a granule-retaining screen, the cut-off of the granule filling being signaled by liquid moving through the screen to a control level thereabove and/or by an increase in the hydraulic pressure of the liquid below the screen. In preferred embodiments the measuring chamber is provided with a flexible wall which is positioned to either increase or decrease the volume of the measuring chamber and thereby selectively vary the volume of the granule increment captivated by the chamber. The invention provides for the pulsing of resin increments of precisely and adjustably metered volume, and provides a means for keeping the loading and regeneration sides of the system in resin transfer balance.

摘要： Apparatus and operating method improvements are provided for an ion exchange apparatus system utilizing moving folded beds for loading and regeneration of the resin. The improvements include separate treatment and pulse chambers in the resin circuit from the loading column to the regeneration column, and in the return circuit from the regeneration column to the loading column. With the improved apparatus and method, the resin is transferred in compacted metered increments from and into the loading and regeneration columns.

摘要： Adsorbed magnesium is removed from a cation exchange resin by elution with 20 to 70% sulfuric acid as increments of the loaded resin move upwardly in a stripping column, the regenerated resin being removed at the top of the column and the sulfuric acid of reduced concentration with the eluted magnesium is removed from the lower portion of the column. The sulfuric acid concentrations are controlled so that the regenerating solution can be formed from commercial concentrations of sulfuric acid without undue dilution, and so that magnesium can be precipitated from the eluting solution by increasing the sulfuric acid concentration without adding a large amount of commercial concentration acid. The amount of dilute sulfuric acid produced as a waste material is kept to a minimum, while the principal sulfuric acid by-produkt has a usefully high concentration, such as may be employed for treatment of phosphate rock.
