1. This precipitate dissolves in an excess of aqueous ammonia.

2. The magnetic field promoting the absorption of aqueous ammonia is a new field for enhancing heat and mass transfer.

3. A new less capital-intensive method utilizes commercially available aqueous ammonia and charcoal produced from co-firing biomass gases for NOx reduction applications.

4. Aqueous ammonia must be hydrolyzed in order to be used, but it is substantially safer to store and transport than anhydrous ammonia.

5. The preparation of ethanolamine is mainly composed of aqueous ammonia and liquid ammonia methods, which belong to typical homogeneous catalysis and heterogeneous catalysis respectively.

6. When utilized in combination with aqueous ammonia scrubbing system for CO2, the two create a nitrogen fertilizer.

6. try its best to gather and create good sentences.

7. From economical view, it is better when inlet concentration of CO2 is above 10%. With raised concentration of aqueous ammonia, it is easy to remove CO2, and the spill of NH3 will be increased.

8. Ethanolamines are commonly made by the method of reacting aqueous ammonia and ethylene oxide. Product profile, product quality and energy consumption are three key factors in ethanolamine process.

9. On the basis of film theory, a simplified macro - kinetics model in carbonization process of aqueous ammonia - mirabilite solution is developed.

10. When the concentration. of ammonia in exit gas is 0.5%, the length of the falling. film tube for the preparation of 65% by weight of aqueous ammonia solution has been taken as 15.5 meters.

11. The direct leaching method of roasted molybdenite with ammonia (or liquid ammonia) instead of aqueous ammonia has been described.

12. Ammonium polymethacrylate (APMA) was prepared from methacrylic acid and aqueous ammonia , then the water-soluble copolymer of APMA-PMMA were synthesized.

13. Advantages and disadvantages of the SNCR denitrification systems were separately compared by using different reactants, such as aqueous ammonia, anhydrous ammonia and urea etc.

14. For a given additive concentration, the surface tension of aqueous ammonia increased with the increase of the ammonia when the concentration was less than 10%.
