[0044] Example 1,
[0045] First, add water and boil the activated carbon as it is in a 500ml beaker for 2 to 4 hours to remove impurities on the surface and pores of the activated carbon, cool to room temperature, filter and dry. Take a 250mL open conical flask and add 50mL dry activated carbon and 0.5mol / L MgCl 2 100mL of the solution, after it is adsorbed until there are no bubbles, put it into a shaker to shake and adsorb for 6-24h. After suction filtration under the circulating water pump, add the activated carbon after suction filtration into a 250mL beaker, and titrate the resulting activated carbon with 1mol / L ammonia. A white gel will appear in the beaker wrapped on the activated carbon. At this time, use a pH meter to constantly monitor the system To the pH value of pH=10, the sample after the precipitation is allowed to stand for 4h. After standing, it is separated by filtration and washed with deionized water until the filtrate in the filter bottle is clarified. At

[0048] Example 2
[0049] The activated carbon is boiled in a 500ml beaker with water for 2 to 4 hours to remove impurities on the surface and pores of the activated carbon, cooled to room temperature, filtered and dried. Take a 250mL open Erlenmeyer flask and add 50mL dry activated carbon 1mol / L 100mL MgCl 2 After the solution is adsorbed without bubbles, it is placed on a shaker and absorbed for 6 to 24 hours. After suction filtration under the circulating water pump, add the activated carbon part after suction filtration into a 250mL beaker, titrate the activated carbon with 1mol / L of ammonia, and a white gel will appear in the beaker wrapped on the activated carbon. At this time, use a pH meter to constantly monitor the system When the pH value in the filter flask reaches pH=10, the sample after the precipitation is allowed to stand for 4h, and then filtered and separated, washed with deionized water until the filtrate in the filter flask is clarified, and the pH value of th

[0052] Example 3
[0053] The activated carbon is boiled in a 500ml beaker with water for 2 to 4 hours to remove impurities on the surface and pores of the activated carbon, cooled to room temperature, filtered and dried. Take a 250mL open Erlenmeyer flask, add 50mL dry activated carbon, 100mL 2mol / L MgCl 2 After the solution is adsorbed without bubbles, it is placed on a shaker and absorbed for 6 to 24 hours. After suction filtration under the circulating water pump, add the activated carbon part after suction filtration into a 250mL beaker, water the activated carbon with 2mol / L ammonia, a white gel will appear in the beaker wrapped on the activated carbon, at this time, use a pH meter to monitor the system constantly When the pH value in the filter flask reaches pH=10, the sample after the precipitation is allowed to stand for 4h, and then filtered and separated, washed with deionized water until the filtrate in the filter flask is clarified, and the pH value of the filtrate
