Hey there Muhammad Tanveer! So, when it comes to extracting both organic carbon (OC) and elemental carbon (EC) from soot for measuring the band gap using the Tauc plot method, you'll want to choose a solvent that effectively dissolves these components. One commonly used solvent for this purpose is a mixture of toluene and acetone.
Toluene is great for dissolving organic components, including OC, while acetone is effective in extracting elemental carbon. The combination of these two solvents provides a comprehensive approach to extracting a wide range of carbonaceous materials from soot.
Here's a suggested procedure:
1. **Prepare the Solvent Mixture:**
- Mix toluene and acetone in a suitable ratio. A common ratio is 1:1, but you Muhammad Tanveer can adjust it based on your specific requirements.
2. **Soot Extraction:**
- Immerse the soot sample in the solvent mixture and let it soak for a sufficient period, ensuring thorough extraction.
3. **Separation:**
- After extraction, you Muhammad Tanveer can use filtration or centrifugation to separate the dissolved components from the insoluble residue.
4. **Analysis:**
- The extracted OC and EC can then be analyzed further for band gap measurements using the Tauc plot method.
Remember, the choice of solvent and its ratio may vary based on the composition of the soot and the specific properties you're aiming to study. Always conduct preliminary tests to optimize the solvent system for your particular soot sample.
While I am very excited to learn more from your research efforts, some of my work on OC and EC might be interesting for you Muhammad Tanveer to read:
