The preparation method can quickly prepare MIL-121 with high thermal stability under ambient pressure, and potentially pave the way for the industrial production of MIL-121. 3.5. Lithium Ion Adsorption Performance The MIL-121 prepared at three different synthesis temperatures and two different scales were polymerized by introducing DMVBA (N,N-dimethyl-vinyl-benzyl-amine) monomer into the pores of MIL-121 by the solution radical polymerization method. MIL- 121 is functionalized, making it a composite material PDMVBA-MIL-121 [18] with both free carboxyl groups and amine groups with adsorption properties. A histogram was made according to the adsorption capacity (Table S5, Supplementary Materials) as shown in Figure 8. It can be clearly seen that MIL-121 prepared at three different synthesis tempera- tures and two different scales has little difference in the adsorption performance of lithium ions after polymerization modification, and the adsorption capacity is basically the same at about 0.18 mmol/g. That is, the small particle size MIL-121 prepared by the hydrothermal method and the MIL-121 prepared by the cooling crystallization method have the same adsorption performance for lithium ions after the polymerization modification. However, compared with the hydrothermal method, the cooling crystallization method can quickly obtain a large amount of MIL-121 under ambient pressure, with better reproducibility and operability.

Sodium hydroxide was used as the promoter in the novel method to promote the coordination be- tween metal ions and ligands of MIL-121 without the reaction condition of high temperature and pressure, so that MIL-121 can be produced under ambient pressure. The experimen- tal result indicates that there is no difference in the lithium-ion adsorption performance between the products of MIL-121 obtained by the cooling crystallization method and hydrothermal method. However, compared with the hydrothermal method, the cooling crystallization method greatly shortens the preparation time and production cost of MIL- 121. In this paper, the optimal synthesis strategy of the cooling crystallization method was also determined and a small-scale cooling crystallization experiment was carried out under the guidance of the optimal synthesis strategy. The MIL-121 products obtained by this method are of a uniform size and higher stability compared with the products prepared by the hydrothermal reaction at the same temperature. The alkali-assisted mechanism of this method was estimated, and effect of reaction condition on the morphology and crystal size of MIL-121 crystal products was investigated. The experimental results demonstrate that the MIL-121 can be produced by the traditional cooling crystallization without high tem- perature and pressure, which provided a basis for the industrialization of aluminum-based MOF (MIL-121).PDF Image | Small Particles for Lithium Adsorption from Brine

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 (Standard Web Page)
