Surfactant

The adsorption kinetics of surfactants onto the crystal surface spin-coated with a thin layer of a model membrane material, polyethersulfone was monitored through measurements of frequency and dissipation shifts simultaneously using a quartz crystal microbalance with dissipation (QCM-D) apparatus. I

The aim of the study was to investigate the simultaneous removal of p -cresol and Cr(III) ions using a membrane contactor enhanced by a micellar solubilization. The investigations of solutes removal were performed taking advantage a polysulfone capillary membrane contactor in a counter-current mode

The aim of the study was to compare the removal efficiency of anionic surfactant (belonging to alkylbenzenesulfonate family) from water solutions by means of ultrafiltration and ion-exchange. During the first stage of the experiments, the influence of surfactant type and its concentration, membrane

The demand for clean water is currently increasing because of the decreasing sources of drinking water the stringent environmental legislation and the rigorous quality demands. Nanofiltration may be a solution for the effective separation of anionic detergents from used water or wastewater. In this

Reactive dyes are non-degradable and toxic to environments and human being, and their solutions have some color even after wastewater treatment. To remove toxic dyes, adsorption is common choice. In this study, to improve the adsorption capacity, the effect of cationic surfactant was studied to remo

In an effort to make wastewater recycling risk-free, this research investigated the feasibility of using a waste material as filter for the removal of humic substances (HS), and ultimately the toxic hydrophobic organic compounds (HOC) attached to them. Based on the results of earlier studies, labora

A low-pressure membrane process was studied in order to treat aqueous solutions containing both dye and surfactant. The influence of various textile dyes (methyl orange, indigo carmine, amido black, titan yellow or direct black) on separation efficiency of surfactants (sodium dodecyl sulphate, SDS)

Ultrafiltration separation of an anionic surface active agent belonging to the alkylsulfonate family was studied. Asymmetric membranes made of polyethersulfone, polysulfone, regenerated cellulose, cellulose acetate and polyamide with a molecular weight cut-off equal to 5, 10 and 30 kDa were used. Th

Electroplating method was employed to recover copper and surfactant simultaneously from synthetic solutions prepared to simulate concentrated waste stream generated from micellar-enhanced ultrafiltration. Effects of surfactant and copper (II) concentrations, surfactant to copper (II) molar ratio (S/

The objective of this study was to investigate the influence of MWCO, pressure, SDS concentration, salt amount and temperature on surfactant removal and permeate flux. Intersep Nadir membranes made from polyethersulphone (PES) and polysulphone (PS) were used. With the addition of a mineral salt to t
