The sodium dodecyl sulfate (SDS) and iso-amyl alcohol were used for this research . The lowest concentration this device could detect DST changes was 45 mg/1 for SDS and 0.020% for iso-amyl alcohol.
WebThe du Noüy–Padday method is a minimized version of the du Noüy ring method replacing the large platinum ring with a thin rod that is used to measure equilibrium surface tension or dynamic surface tension at an air–liquid interface. In this method, the rod is oriented perpendicular to the interface, and the force exerted on it is measured.
