Dear professor and friends,
Many reports suggested that ammonium nitrate + Ethanol can be used to remove CTAB from newly synthesized MSN. But in our place (India) ammonium nitrate is banned due to safety reasons.
Some papers suggested calcination but it may affect the nature of MSN and it has few demerits.
Is there any alternative way to effectively remove CTAB? Con HCl + Ethanol will be a safe method for removal of CTAB from MSN?
Please give your answers
Thank you.
