added and dissolved into the solution. The dosage of sodium thiosulfate and sodium sulfite was 15.8 g/L (=0.1 mol/L) and 12.6 g/L (=0.1 mol/L) respectively. Then, 0.75 g of FP was added, which gave the dosage of 7.5 g/L or 0.05 mol/L. A lid was placed on the bottle and it was shaken for 24 hours on the water bath shaker at 100 rpm at 25, 45 or 65 °C. The pH was uncontrolled or controlled at 5, 7 or 9 with sodium hydroxide. During the 24 hour experiment, 0.1 mL samples of the solution were taken several times at a certain time for ICP analysis. All the samples for ICP analysis were diluted 1000 times in solution with 2% of nitric acid (HNO3). After 24 hours, the powder was washed with DI water three times, vacuum filtered and dried at 60–65 °C for stripping experiments or for XRD analysis or acid digestion. 3.3.3. LithiumStrippingTest A lithium stripping test was carried out after each loading test to see how much lithium could be recovered from LFP back into solution. The dried powder after loading was used for batch-style stripping test. A stripping method is same as that of preparation of FP, but the volume of solution was varied. A mass of 0.63 g of LFP was put into 20 mL of 0.2 M K2S2O8 (LFP:PS=1:1) and shaken for 24 hours on the shaker at 220 rpm and ambient temperature. After 24 hours, the powder and solution were recovered and treated for XRD and digestion/ICP analysis in the same way above. 3.3.4. Acid Digestion In order to analyze an exact ratio of elements in the solid, FP or LFP powder was digested with concentrated HCl. In a small beaker, 0.01 g of FP or LFP was reacted with 5 mL of 38% HCl and 5 mL of DI water for an hour under a fume hood. After one hour, all the solution was filtered, - 71 -PDF Image | LITHIUM EXTRACTION FROM BRINE using ion resin

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.| CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com | RSS | AMP |
