[0013] Example 1
[0014] The material of this example is ivory white in appearance. XRD test showed that its structure is hexagonal, and its main compound is hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 . X=0.5, Y=0.2, R=Fe 3+ Load Ti 4+ Hydroxyapatite adsorbs a disinfecting material and determines the chemical expression of the material (Ca 9.3 Ti 0.5 Ag 0.2 )(PO 4 ) 6 (OH) 2 .
[0015] Synthesis of nano-scale Ti loaded by hydrothermal method 4+ The hydroxyapatite adsorption disinfection material is to first configure the (Ca+Ti+Fe) composite solution, and the (NH 4 )H 2 PO 4 The solution was stirred and added dropwise to a (Ca+Ti+Fe) composite solution at a temperature of 100°C, where the molar ratio of (Ca+Ti+Fe) / P was 1.9. Then add dropwise ammonia or acid to adjust the pH of the solution and keep the pH at 8. After repeated centrifugal separation and washing with water three times, white precipitate A is obtained; the white precipitate A is put into a hydrothermal reactor for hydro...

[0021] Example 3
[0022] The material of this example is white in appearance. XRD test showed that its structure is hexagonal, and its main compound is hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 . X=6, Y=0.02, R=Ce 4+ Load Ti 4+ Hydroxyapatite adsorbs and disinfects the material and determines the chemical expression of the material (Ca 3.98 Ti 6 Ce 0.02 )(PO 4 ) 6 (OH) 2 .
[0023] Synthesis of nano-scale Ti loaded by hydrothermal method 4+ The hydroxyapatite adsorption disinfection material is to first configure the (Ca+Ti+Ce) composite solution, and the (NH 4 )H 2 PO 4 The solution was stirred and added dropwise to the (Ca+Ti+Ce) composite solution at a temperature of 20°C, where the molar ratio of (Ca+Ti+Ce) / P was 1.50. Then add dropwise ammonia or acid to adjust the pH of the solution and keep the pH at 12. After repeated centrifugal separation and washing with water three times, white precipitate A is obtained; the white precipitate A is put into a hydrothermal reactor for hydro...
