Embodiment 1
[0024] Step a: Preparation of Nano-AgCl Particles
[0025] 1 part of polyvinylpyrrolidone (hereinafter referred to as PVP) K90 powder was dissolved in 39 parts of deionized water as a mother solution, and the temperature of the mother solution was controlled at 15°C. Add 12 parts of 50wt% silver nitrate aqueous solution and 10 parts of 20wt% sodium chloride aqueous solution dropwise to mother liquor simultaneously with the speed of 2ml / min, stir and react for 30 minutes, obtain 62 parts of nano-AgCl dispersion liquids with an average particle diameter at 300nm.
[0026] Step b: Isolation of Nano-AgCl Particles
[0027] Add 31 parts of absolute ethanol to the AgCl dispersion prepared in step a, and place it in a water bath to keep the temperature at 60°C. Add 1 part of 30% oleic acid / ethanol solution and stir for 15 minutes. After static separation, the Ag / Cl particle precipitate was obtained by filtration.
[0028] Step c: AgCl carrier preparation
[0029] Add the precipit...
