A rapid,accurate nuclear magnetic resonance(NMR) spectrometric technique was developed for the qualitative and quantitative analysis of multicomponent surfactant combinations.The efficient methods for the separation and identification of multicomponent surfactant mixtures were investigated in detail.The main characteristic peaks in the NMR spectra of surfactants were assigned,and the surfactant contents were obtained by NMR signal component analysis.The experimental results confirmed that NMR spectroscopy can be used to quantify the structures of surfactants in multicomponent systems.
