I am working with production of biosurfactants from bacteria is their any method to identify the change ( cationic anionic or nonionic) by conventional spectroscopic method.
Most commonly, surfactants are classified according to polar head group. A non - ionic surfactant has no charged groups in its head. The head of an ionic surfactant carries a net positive or negative charge. If the charge is negative, the surfactant is more specifically called anionic; if the charge is positive , it is called cationic.. If the surfactant contains a head with two positively charged groups, it is termed zwitterionic.. For more details consult https://www.en.m.wikipedia.org
Hello Karanam, Yes, of course there is. Generally, one of the main applications of spectrophotometric techniques has been routine environmental analysis due to their quickness and simplicity. They involve the formation of ion associates of analytes with specific ion-pair reagents and their extraction into appropriated organic solvents. See the attached
@ Maurice thank you for the information which is interesting. However the complication in my work is the type of surfactant that I am producing is unknown and the raw material that I am using municipal waste. So resultant surfactant after extraction is darker in colour and theoretical it do have a combination of surfactant, which makes the identification process more complex
