There are many methods for determining surfactants i.e. absorption spectrophotometry, IR, electricity tension, luminosity, analytical method and HPLC.

It successfully applied to determination of low concentration of cationic surfactants in the domestic sewage and Xian city moat.

Recently, spectrophotometric methods based on ANNs have found increasing applications for simultaneous determination.
