Embodiment 1
[0030] 90mL of distilled water was added to a 250mL three-necked flask, and 8.8g of FeCl 2 4H 2 O, 22g FeCl 3 ·6H 2 O was placed therein, and stirred until the solid in the three-necked flask was completely dissolved. When the temperature was heated to 80°C, high-purity nitrogen gas was introduced to remove the oxygen in the reaction device, and 55 mL of NH 3 ·H 2 O (25%), after continuing to react for 30 min, 0.9 mL of oleic acid was added dropwise into the three-necked flask, and the temperature was raised to 85° C. for 180 min. The resulting product was washed several times with distilled water to remove unreacted oleic acid. After high-temperature drying, grinding, and finally get Fe 3 o 4 Nanoparticles.
[0031] Weigh the Fe obtained in the above steps 3 o 4 0.05g, add 40mL of absolute ethanol and 10mL of deionized water into a 250mL three-neck flask, after mixing, use an ultrasonic instrument to vibrate for 20min, and add 0.5mL of NH 3 ·H 2 O (28%), after sti...
Embodiment 2
[0036] 100mL of distilled water was added to a 250mL three-necked flask, and 9.8g of FeCl 2 4H 2 O, 24g FeCl 3 ·6H 2 O was placed therein, and stirred until the solid in the three-necked flask was completely dissolved. When the temperature was heated to 80°C, high-purity nitrogen gas was introduced to remove the oxygen in the reaction device, and 50 mL of NH 3 ·H 2 O (25%), after continuing the reaction for 30 min, 1 mL of oleic acid was added dropwise to the three-necked flask, and the temperature was raised to 85° C. for 180 min. The resulting product was washed several times with distilled water to remove unreacted oleic acid. After high-temperature drying, grinding, and finally get Fe 3 o 4 Nanoparticles.
[0037] Weigh the Fe obtained in the above steps 3 o 4 0.1g, add 80mL of absolute ethanol and 20mL of deionized water into a 250mL three-neck flask, after mixing, use an ultrasonic instrument to vibrate for 20min, and add 1.0mL of NH3 ·H 2 O (28%), after stirr...
Embodiment 3
[0042] 110mL of distilled water was added to a 250mL three-necked flask, and 10.8g of FeCl 2 4H 2 O, 27g FeCl 3 ·6H 2 O was placed therein, and stirred until the solid in the three-necked flask was completely dissolved. After the temperature was heated to 80°C, high-purity nitrogen gas was introduced to remove the oxygen in the reaction device, and 65mL of NH 3 ·H 2 O (25%), after continuing to react for 30 min, 1.1 mL of oleic acid was added dropwise into the three-necked flask, and the temperature was raised to 85° C. for 180 min. The resulting product was washed several times with distilled water to remove unreacted oleic acid. After high-temperature drying, grinding, and finally get Fe 3 o 4 Nanoparticles.
[0043] Weigh the Fe obtained in the above steps 3 o 4 0.2g, add 160mL of absolute ethanol and 40mL of deionized water into a 500mL three-neck flask, after mixing, use an ultrasonic instrument to vibrate for 20min, and add 2.0mL of NH 3 ·H 2 O (28%), after s...
