I am reading an article about Graphene based solid phase extraction disk for separation of polycyclic aromatic hydrocarbons.The procedure contains preparation of 200 mg of graphene dispersed in water under ultrasound for 30 minutes using a glass fiber filter under vacuum.
Dear Stefano,
I think you are reading the article of Zonghua Wang (DOI 10.1002/jssc.201300186). I would like to know what thickness you need of your disk. Accordingly we can choose the method for its' preparation.
Yes, I am speaking about that article.
Application is about polycyclic aromatic hydrocarbon. I don't undersand the paragraph 2.4 that speaks about how to make a disk.
Thank you
Stefano
Solid phase micro extraction (SPME) would give better performance instead of SPE. The attached file might give some thought of SPME comparison with other extraction tools.
I agree with Dr. Mottaleb with the idea of using SPME for the analysis of PAHs. The SPME approach is much easier to operate, especially if the equilibrium times are within a practical range. There are numerous reports on the preparation of Graphene based SPME coatings.
