Preparation method of bone char fluoride removal agent loaded with aluminium ions

[0019] The production method of loaded aluminum ion bone charcoal defluoridation agent is carried out according to the following process:

[0020] 1. Weigh 5g of bone char and put it into 60mL aluminum nitrate solution with an aluminum ion concentration of 1.2g / L;

[0021] 2. Put the bone charcoal and solution mixture into a shaker, shake at 20°C, 100rpm for 24 hours;

[0022] 3. After shaking, take out the bone charcoal, rinse it with clean water several times and dry it.

[0024] The production method of loaded aluminum ion bone charcoal defluoridation agent is carried out according to the following process:
