摘要: The present invention comprises a supported liquid membrane carrier liquid with a dielectric constant between approximately 20 and 32, more particularly between 22 and 28, and preferably about 24, and the use of that carrier liquid in a supported liquid membrane device to extract one or more chemical species from a feed liquid. The invention further comprises such a device where a temperature gradient is maintained between any of the feed, carrier, or strip liquids. In another embodiment of the invention, any of the feed, carrier, or strip liquids are conditioned, for example, by passing the liquids through a purifier, or replacing lost carrier liquid. In another embodiment of the invention, two or more devices are connected in series or parallel.

摘要: Methods for synthesizing nano-urea particles are described. The methods involve using a spinning cone reactor, a nano-channel reactor, combustion synthesis or spray drying. Ammonia and carbon dioxide are used as raw materials for producing urea. The methods allow for the production of urea nanoparticles at high conversion rates. The methods allow for better control over the hydrolysis rate of the nano-urea particles. The nano-urea particles can be used as fertilizers and provide for sustained release of ammonia and its conversion to nitrates in the soil. The nano-urea particles have low volatilization rates, low moisture absorption rates and low biuret concentration. The nano-urea particles can be applied to the soil via fertigation.
