I saw cationic surfactants like DTAB, TTAB, and CTAB. Which surfactant should I choose was a problem. The one with low cmc or one with high cmc would help in separation of oil and water?
Normally Cationic surfactants are expensive and use for change the wettability from oil wet to water wet conditions. Cationic surfactants also reduces the IFT.
Do not use from these DTAB, TTAB, and CTAB .
Why? Because it is already used by so many researchers.
I will try to look for some alternative surfactants then.
By using low CMC one, the oil will be separated fast, right sir? By formation of Micelles earlier.
One doubt I had, after the operation, will the mixture of surfactant and oil float on the top, below that water and at the bottom, iron fines. Right sir?
