摘要： A process of fluoride removal from wastewater streams produced during industrial operation for further industrial use or to comply with environmental regulations. The process segregates the removal of fluoride and fluorosilicate ions, from the totality of ions in the wastewater stream, thus improving treatment efficiency and reducing costs. Ion-exchange chromatography is used to remove the fluoride and fluorosilicate ions by passing the wastewater stream through one or more columns that contain a charge resin, which selectively binds cations/anions in the stream. The fluoride ions are washed from the column and then collected for removal or use in other processes.

摘要： A method and apparatus for treating an electroless plating solution is provided. The apparatus includes a reaction vessel, a cathode and an anode disposed in the interior of the reaction vessel and in electrical communication with a power source, a drain disposed in the reaction vessel, and a nozzle in fluid communication with the drain, disposed in the reaction vessel such that the nozzle and the drain are separated by the cathode and the anode. The method includes disposing an electroless plating solution in the reaction vessel, recirculating the plating solution through the reaction vessel by draining the plating solution from the reaction vessel and subsequently re-injecting the plating solution into the reaction vessel through the nozzle. A current is driven through the anode and cathode to oxidize reducing agents in the liquid and plate out the metal as the elemental metal.

摘要： A method for removing fluorine gas from a selected environment comprises contacting the fluorine gas with water to generate a solution of hydrofluoric acid and contacting the solution of hydrofluoric acid with an ion exchange resin having an active state operative to exchange selected ions therein for fluoride ions in the solution. The apparatus (200) may include a dual resin setup (222, 223) such that one of the ion-exchange resin can be in the service cycle while the other of the ion-exchange resins undergoes the regeneration and rinse/refill cycles.
摘要翻译：从所选择的环境中除去氟气的方法包括使氟气与水接触以产生氢氟酸溶液，并使氢氟酸溶液与具有活性状态的离子交换树脂接触，以在其中交换选定的离子以进行氟离子解决方案。装置（200）可以包括双重树脂装置（222,223），使得一个离子交换树脂可以处于使用循环中，而另一个离子交换树脂经历再生和冲洗/再填充循环。
