Certain time, then it is centrifuged, it is Sargent gloryvine extract solution to take supernatant；
Step 2, it is at room temperature, described redder than the chlorauric acid solution that concentration is 0.1mol/L is added to by predetermined volume
Reacted 0.5~10 minute in rattan extract solution, reaction obtains reaction solution after terminating, and the reaction solution is centrifuged and sunk
Starch；
Step 3, processing is dried in the sediment, obtains gold nano grain.
Using Sargent gloryvine extract solution the method for gold nano grain is prepared provided by the invention, can also had such special
Sign：Wherein, boiling continues 5~15 minutes in step 1.
Using Sargent gloryvine extract solution the method for gold nano grain is prepared provided by the invention, can also had such special
Sign：Wherein, the predetermined volume in step 2 than being for the volumetric ratio of the chlorauric acid solution and the Sargent gloryvine extract solution
0.0025:3~0.01:3.
The effect of invention and effect
The method that gold nano grain is prepared using Sargent gloryvine extract solution involved in the present invention because Sargent gloryvine extract solution facilitate it is easy
, it is cheap and there is no toxicity, the chemical reagent used in the past is replaced using it as reducing agent, has green, is synthesized
The advantages that speed is soon and economy is high；Secondly because reaction is carried out at normal temperatures, thus preparation technology is simple, safe operation just
