130, by the method for ultrasonic agitation, the compound particles are dissolved.
The ultrasonic agitation can carry out in the solvent of any suitable type, such as water or other are suitable organic molten
Agent keeps compound particles fully dispersed in a solvent, achievees the effect that remove the impurity such as the presoma not reacted in mixture.
140, dialysis removes unreacted nitrogenous or sulfur-bearing hydrocarbons in the compound particles, obtains the nitridation
Carbon colloid.
Further unreacted nitrogenous or sulfur-bearing hydrocarbons are removed by the method for dialysis in step 140
To prepare pure nitridation carbon colloid.These nitridation carbon colloids are anti-by nitridation carbon dust and nitrogenous or sulfur-bearing hydrocarbons
It should obtain, surface graft has the functional group of modification, has extraordinary dispersibility.
In some embodiments, the method for the dialysis can be specifically achieved by the steps of:
Firstly, taking the dissolved upper turbid solution of the compound particles.
The impurity such as the presoma not reacted due to dispersibility etc. problem, and insoluble in solvent.Therefore, muddy in absorption
After turbid, the first separation for compound particles can be realized.
Then, turbid solution on this is placed in bag filter to be placed in dialysis solvent and is dialysed.
Bag filter is can to function similarly to the effect of sieve selectively penetrating pocket made of film.It is molten dialysing
Under the osmotic pressure effect of liquid, unreacted nitrogenous or sulfur-bearing hydrocarbons are precipitate into dialysis solvent in turbid solution in order.
Specifically, the aperture of the bag filter can be 3500kDa.The dialysis solvent is water, ethyl alcohol or methanol.When
So, technical staff can also select suitable bag filter according to the molecular dimension of nitrogenous or sulfur-bearing the hydrocarbons of actual use
Aperture.
Finally, obtaining the nitridation carbon colloid after the dialysis time of setting.It is stagnant after sufficient dialysis time
The liquid stayed in bag filter is pure nitridation carbon colloid, and unreacted nitrogenous or sulfur-bearing hydrocarbons can be gone
It removes.
Specifically, the dialysis time is 1-15 days, so that unreacted nitrogenous or sulfur-bearing hydrocarbons are abundant
Removal.
