Embodiment 1
[0033] Measure 500ml of n-heptane and put it in a beaker, and slowly add 120g of surfactant ST with electromagnetic stirring. Measure 1.5M FeCl 3 40ml of aqueous solution, 1.5mL of glacial acetic acid was added dropwise, and then the mixed liquid was added dropwise into the oil phase liquid of n-heptane, and the uniform solution was an orange-red turbid liquid. Measure 13ml of n-butanol, add dropwise to the turbid liquid, then the liquid becomes clear and transparent, and finally forms a W / O microemulsion liquid. 60ml, 1.5M NH 4 h 2 PO 4 Mix with 15ml, 0.5M sodium acetate solution evenly, add evenly and slowly with a burette, the solution system gradually changes from orange-red transparent to orange-red turbid, and finally becomes a white milky dispersion solution system. Heat the solution system to 70°C and keep it warm for 10 minutes, and the oil and water of the solution system are separated. Wash with acetone, soak the aqueous phase, and collect the precipitate. Dry...
Embodiment 2
[0035] Measure 500ml of n-heptane and put it in a beaker, and slowly add 120g of surfactant ST with electromagnetic stirring. Measure 0.1M FeCl 3 40ml of aqueous solution, 2.5mL of glacial acetic acid was added dropwise, and then the mixed system was added dropwise into the oil phase liquid of n-heptane, and the solution became an orange-red turbid liquid after being uniform. Measure 5ml of n-butanol, add dropwise to the turbid liquid, then the system becomes clear and transparent, and finally forms a W / O microemulsion liquid. 80ml of 0.8M NH 4 h 2 PO 4 Mix evenly with 20ml 0.8M lithium acetate solution, add evenly and slowly with a burette, the solution gradually changes from orange-red transparent to orange-red turbid, and finally becomes a white milky dispersed solution system. Heat the system to 70°C and keep it warm for 10 minutes, and the oil and water of the solution system are separated. Wash with acetone, soak the aqueous phase, then collect the precipitate, and ...
Embodiment 3
[0037] Measure 500ml of n-heptane and put it in a beaker, and slowly add 120g of surfactant ST with electromagnetic stirring. Measure 0.05M FeCl 3 40ml of aqueous solution, add 4mL of glacial acetic acid dropwise, and then add the mixed liquid dropwise into the oil phase liquid of n-heptane, the liquid will gradually become clear and transparent, and finally directly form a W / O microemulsion liquid. 60ml 1M NH 4 h 2 PO 4 Mix evenly with 30ml 1M potassium acetate solution, add evenly and slowly with a burette, the solution changes from orange-red transparent to orange-red turbid, and finally becomes a white milky dispersion system. Heat the liquid to 70°C and keep it warm for 10 minutes. The oil and water in the system are separated. Wash with absolute ethanol, soak the water phase, then collect the precipitate, and dry the precipitate at 300°C for 12 hours. The material was then soaked in 1M LiI for 24 hours, filtered, washed and the precipitate collected. The final prec...
