Example Embodiment
[0027] Example 1:
[0028] Carrier material: resin-based spherical activated carbon, produced by Shanxi Cuihong Technology Co., Ltd., the diameter of the ball is 0.3-1.2mm, and the specific surface area (BET) is 950-1200 (m) 2 / g), pore volume 0.6-0.75ml / g.
[0029] Preparation:
[0030] 1). Preparation of carrier:
[0031] The resin-based spherical activated carbon is transferred to a tubular electric furnace with nitrogen flow for pyrolysis, and slowly rises from room temperature to 800°C at a temperature rise rate of 80°C per hour. When the temperature is reached, the nitrogen is switched to 5L / hour flow rate hydrogen fluoride activation treatment 5 After hours, the product was cooled to room temperature. Get the carrier.
[0032] 2). Load operation
[0033] Soak the carrier in trifluoroacetic acid 1.8 times its mass for 4h, add 8% neodymium trioxide of carrier mass and 0.3% citric acid of carrier mass at the same time, react at 60℃ for 15h, finally wash with ethanol and dry , The ...
Example Embodiment
[0034] Example 2
[0035] In step 2), the amount of neodymium trioxide added was changed to 5% of the carrier mass, and the others were the same as in Example 1. The product number obtained is M-2.
Example Embodiment
[0036] Example 3
[0037] In step 2), the amount of neodymium trioxide added was changed to account for 10% of the carrier mass, and the others were the same as in Example 1. The product number obtained is M-3.
