Study on the Monolayer Dispersion of SrCl₂ onto Silica Gel and Its Ammonia Adsorption

On the basis of theory of "Spontaneous Monolayer Dispersion of Oxides and Salts onto Surface of Supports", the effects of different calcination temperatures, load capacities on the monolayer dispersion of SrCl₂ onto silica gel were studied by XRD, and the ammonia adsorption of samples was measured. It indicates that it is optimal to calcine samples at 500℃ for the monolayer dispersion of SrCl₂ onto silica gel, and the monolayer dispersion threshold is lower than 0.3g/g. Ammonia adsorption capacity of the sample calcined at 500℃ is the strongest in the different calcination temperatures. Ammonia pressure has different effects on ammonia adsorption capacity to different load samples.
