Surfactants are one of the major components (10- 18%) of detergents and household cleaning products and are used in high volumes in developed countries. In the present research work, the ability of rice husk as a low cost adsorbent for anionic and nonionic surfactants in wastewater has been studied. The maximum removal efficiency for anionic surfactants was 97%, in an aqueous solu...

Application of surfactants to increase the mobility of hydrophobic contaminants in soils will create a secondary aqueous waste stream containing mobilized contaminant and surfactant that may be biodegraded. Previous research on surfactant biodegradation focused on low surfactant concentrations, typically less than 0.01 % (weightlweight). The goal of this project was to investigate the effect of...

Biofouling of surfaces is a major cause infection and leads to significant patient morbidity mortality within healthcare settings. With ever-increasing concerns over antibiotic resistance associated challenges in eradicating surface-attached biofilm communities, efficacious antifouling materials are urgently required. We herein describe the development an inherently antiadherent polymer system ...

Abstract The performance of a rheological model that accounts for the effect volume fraction, particle size distribution, and shear rate on viscosity water-borne dispersions stabilized with conventional nonionic surfactants polymeric stabilizers is assessed. contains three parameters fitted well experimental data. were independent rate. Furthermore, two them not affected by surfactant type conc...

Abstract The paper shows that oil pollution of gray forest and soddy-podzolic soils led to a decrease in capillary water capacity, plasticity solid phase soils. As result the introduction nonionic surfactant tween-80 into oil-contaminated soil, these indicators were partially restored, but their values remained lower than soil samples subjected treatment. obtained materials allow us speak about...

The effect of nonionic surfactant micellar (Triton X–100) on the sensitive, simple and inexpensive, spectrophotometric method was developed for the determination of lead (II) with isonitriso p-isopropyl acetophenone phenyl hydrazone (HIPAPH). Lead was complexed with isonitriso p-isopropyl acetophenone phenyl hydrazone (HIPAPH) in presence of non ionic surfactant micellar (Triton X–100). Absorpt...

The interaction of polyvinylpyrrolidone (PVP) with an anionic surfactant (sodium dodecyl sulfate, SDS), a nonionic surfactant (pentaethylene glycol monodecyl ether, C(10)E(5)), and a zwitterionic surfactant (lauryl amido propyl betaine, LAPB) has been investigated by means of pulsed gradient spin-echo NMR (FT-PGSE NMR), allowing self-diffusion coefficients to be determined. The results confirm ...
