Embodiment 1
[0036] The preparation method of the nano-iron particle of green synthesis, comprises the steps:
[0037] 1) Weigh 60g of dried water hyacinth stem and leaf powder, place in 1L of deionized water, and extract in a water bath at 80°C;
[0038] 2) The extracted extract was vacuum filtered, centrifuged at 12000 rpm, passed through a 0.45 μm filter membrane, and the filtrate was refrigerated at 4°C in a refrigerator;
[0039] 3) Take 100ml water hyacinth stem and leaf extract and 50ml of 0.15moL / L FeCl 3 The solution is mixed and reacted under the protection of protective gas argon at a volume ratio of 2:1, and the color of the solution turns black under stirring, and a solution containing green synthesized nano-iron is obtained;
[0040] 4) Centrifuge the generated material at 12,000 rpm, wash the centrifuged material twice with acetone and ethanol, and dry at 50° C. in a vacuum oven to obtain a brown-black solid, which is green synthesized nano-zero-valent iron particles.
