The adsorption of Na-dodecylbenzenesulfonate (Na-DBS) onto the polyvinylalcohol Vinylon fiber was investigated. The adsorbed amount of Na-DBS was determined using the ultraviolet spectrum of the wavelength in 224 and 261mμ. The experimental errors by this method were about 3 to 12%.
The maximum adsorption at the adsorption isotherm was recognized distinctly at 25°C, but that was not clear at 30°C. The occupied area of Na-DBS onto Vinylon fiber at maximum adsorption was 1, 040Å2/molec. at 25°C and 2, 250Å2/molec. at 30°C, respectively.
