This paper describes the ordering degree of anionic, cationic, and zwitterionic surfactants with the increase of their packing density on Ge substrate by using Fourier transform infrared-attenuated total reflection (FTIR-ATR) spectroscopy. This
The anionic polyacrylamide concentration was established using hyamine 1622 []. The absorbance of white PAM-hyamine complex was measured spectrophotometrically (spectrophotometer Carry 1000 , Varian) at the wavelength 500 nm after 15 min of the
