Embodiment 1
[0017] a).Nano Fe 3 o 4 The preparation process is: using NH 3 ·H 2 O as a precipitant, first configure a certain amount of FeCl 3 and FeCl 2 mixed solution, and then the NH 3 ·H 2 O was added to the above solution, where Fe 2+ : Fe 3+ :OH - The molar ratio of ion concentration is 1:2:12, vigorously stirred, and kept at constant temperature in a water bath of 30°C. During the reaction, the pH value was controlled at 10. After the mixture gradually turned from orange red to black, the reaction was terminated after stirring for another 15 minutes. The precipitate was heated at 80° C. for 30 minutes, centrifuged, and washed several times with deionized water and ethanol solution. The supernatant liquid was removed, and the product was dried in a vacuum electric furnace at a temperature of 70° C. for 24 hours, and then ground to obtain nanometer magnetic ferric oxide particles.
[0018] b). Preparation of buffer solution: the solution contains 0.003mol / L of Na 3 PO 4 ...
Embodiment 2
[0022] a).Nano Fe 3 o 4 Preparation: with NH 3 ·H 2 O is a precipitant, adding FeCl 3 and FeCl 2 The mixed solution, ion molar ratio: Fe 2+ : Fe 3+ :OH - 1:1:10; at 20°C, stir vigorously at constant temperature for 25 minutes. During the reaction, the pH value was controlled at 9. The precipitate is separated by centrifugation, dried at a constant temperature of 65°C, and ground to obtain nano-magnetic ferric oxide particles.
[0023] b). The preparation of the buffer solution: the buffer solution is composed of Na 3 PO 4 Mixed with NaCl. Na in buffer solution 3 PO 4 The concentration of NaCl is 0.002mol / L, and the concentration of NaCl is 0.05mol / L. The pH of the buffer solution is 5.5.
[0024] C). Preparation of covalent bond type polyacrylic acid magnetic ion exchange resin: in every liter of buffer solution, add 32g of previously prepared Fe 3 o 4 powder, and then quantitatively add carbodiimide solution at 0.0lg / ml. At a constant temperature of 0°C, rea...
Embodiment 3
[0026] a).Nano Fe 3 o4 Preparation: with NH 3 ·H 2 O is a precipitant, adding FeCl 3 and FeCl 2 The mixed solution, ion molar ratio: Fe 2+ : Fe 3+ :OH - The ratio is 1:3:15; at 45°C, stir vigorously at constant temperature for 35 minutes. During the reaction, the pH value was controlled at 11. The precipitate is separated by centrifugation, dried at a constant temperature of 75°C, and ground to obtain nano-magnetic ferric oxide particles.
[0027] b). The preparation of the buffer solution: the buffer solution is composed of Na 3 PO 4 Mixed with NaCl. Na in buffer solution 3 PO 4 The concentration of NaCl is 0.004mol / L, and the concentration of NaCl is 0.15mol / L. The pH of the buffer solution is 6.5.
[0028] c). Preparation of covalent bond type polyacrylic acid magnetic ion exchange resin: in every liter of buffer solution, add 16g of previously prepared Fe 3 o 4 powder, and then quantitatively add carbodiimide solution at 0.03g / ml. At a constant temperature...
