I have prepared nanoparticles, I want to know how to remove surfactant for the preparation?
Be aware that if you remove the surfactant nanoparticles will likely be destabilized.
For inorganic nanoparticles you may calcine them.
Friend, if you use surfactant then the surface property of the nano-particles get changed you can monitor it using any of the existing spectroscopy tools very easily in :
UV vis, PL, FTIR etc ...if you have SEM then you can visualize the difference.
See we use surfactant of different kind based on the nature of our objective (like cationic, anionic, non-ionic surfactant) , most of them use to prevent nanoparticles from aggregation and are volatile in nature so in case of deposition just heating it you can remove surfactant from the particles surface.
And the other process if you have to remove surfactant in solution phase then you have to use respective detergent depending upon the nature of your surfactant.
