水相测定,比如

Solvent-Assisted Thermal Reduction of Graphite Oxide
J. Phys. Chem. C 2010, 114, 14819–14825
The sample for UV characterization was obtained by taking 100 μL of suspension from the flask, which was diluted with equal amount of H2O.

不好意思,有点没对哈,全文如下

The sample for UV characterization was obtained by taking 100 μL of suspension from the flask, which was diluted with equal amount of H2O. After termination of the thermal treatment, the remaining suspensions were filtrated, washed by ethanol, and dried in air.(要干燥的)
…………UV spectra were measured by UV-2450 (Shimadzu Co.).…………
