Effects of Several Nonionic and Anionic Surfactants on Cucumber Protoplasts*
The effects of four nonionic and two anionic surfactants on cucumber protoplasts were examined by light and electron microscopy. Two nonionic surfactants, polyoxyethylene (POE) (n=10) nonylphenylether and POE (n=5) laurylether, caused swelling of protoplasts, followed by their bursting. The bursting gave more destructive effects preferentially on lamellar structures of chloroplasts than the swe...
متن کاملAdsorption relaxation for nonionic surfactants under mixed barrier-diffusion and micellization-diffusion control.
Relaxation processes of surfactant adsorption and surface tension, which are characterized by two specific relaxation times, are theoretically investigated. We are dealing with fluid interfaces and small initial deviations from equilibrium. For surfactant concentrations below the critical micellization concentration (CMC), we consider adsorption under mixed barrier-diffusion control. General an...
متن کاملSurfactant Precipitation in Aqueous Solutions Containing Mixtures of Anionic and Nonionic Surfactants
The sal inity tolerance (precipitation phase boundary) is measured for a mixed anionic/nonionic surfactant sy s t em above the CMC. For any total surfactant concentration, the salinity tolerance is shown to increase as the percentage of nonionic surfactant in the s y s t e m is increased. A model is developed which can predict the phase houndaries for the mixed surfactant s y s t e m from the p...
متن کاملEvaluation of the Effect of Nonionic Surfactants and TBAC on Surface Tension of CO2 Gas Hydrate
Given that most of the gaseous constituents of industrial chimneys are usually carbon dioxide which is one of the most important greenhouse gases. It seems that the hydration process is one of the newest methods for the separation of this gas from gaseous mixtures. In the gas hydrate formation industry, in addition to disadvantages, there are some advantages such as gas separation, transmission...
متن کاملStudy of the Cloud Point of Nonionic Surfactant and Nonionic-cationic Surfactant Mixture: Effect of Electrolytes
Clouding phenomenon generally occurs with nonionic surfactants when the temperature of the system is raised to a certain value. This critical temperature is termed the cloud point (CP). The aqueous solutions of nonionic surfactants show complex phase behaviour including liquid-liquid phase separation at this temperature. The cloud point of aqueous surfactant solutions is influenced by the prese...
