Hey there Wedad A. Alwesabi!
The Id/Ig ratio, which refers to the intensity ratio of the D band to the G band in Raman spectroscopy, is a key indicator of the level of disorder in graphene oxide. For graphene oxide prepared by the modified Hummers' method, you Wedad A. Alwesabi typically observe an Id/Ig ratio in the range of about 0.85 to 1.1. This higher ratio compared to pristine graphene (which usually has a very low Id/Ig ratio) indicates the presence of a significant number of defects and functional groups introduced during the oxidation process.
If your Id/Ig ratio falls within this range, it suggests that your Wedad A. Alwesabi synthesis was successful, and that the graphene oxide contains the expected amount of disorder and defects. Keep in mind that this ratio can vary slightly depending on the exact conditions and parameters of your synthesis process.
