Table A.6 Retention values for Na+, K+, Mg2+ and Li+ with PES membrane at varying pH values. pH 7.1 0 7.5 0.02 8.25 0.01 9.5 0.03 10.1 0.03 0.03 0.04 0.03 0.04 0.04 0.04 0.05 0.05 0.05 0.07 Retention Retention Retention Retention (Mg2+) (Total) 0.05 0.12 0.01 0.10 0.03 0.12 0.10 0.23 0.07 0.22 Retention (Li+) (Na+) (K+) As it is obviously deduced from Table A.6, retention values for lithium near foreign ions are smaller which means that the membrane does not have selectivity towards lithium. Mg2+ ions have the highest retention value around pH=9.5. It can be explained by the +2 charge, which attracts magnesium towards slightly negative sulfur more than other cations. When we look to the total retention values and compare them with the values in Table A.6, it is seen that the capacity of membrane to hold cations is somewhat filled by separate individual cations. The small difference in total retention values can be attributed to the steric effects especially caused by the magnesium ion which is the largest cation among them with the highest charge. 152PDF Image | SEPARATION OF LITHIUM FROM BRINES

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 |
