Oil-water separation has recently become a global challenging task because of the frequent occurrence of oil spill accidents due to the offshore oil production and transportation, and there is an increasing demand for the development of effective and inexpensive approaches for the cleaning-up of the oily pollution in water system. In this study, a self-cleaning underwater superoleophobic mesh t...

membrane module is very important in view of decreasing weight of the separation system. The amounts of supplying water need to be increased in order to enhance separation of dissolved oxygen from water for same membrane module. If the number of membrane modules is decreased, both of size and weight of separation system are decreased and it leads to favorable condition in view of commercializin...

In this study, we fabricated a superhydrophilic and underwater superoleophobic protonated melamine sponge for effective separation of water-rich immiscible oil/water mixtures with extremely high separation efficiency. This protonated melamine sponge exhibited excellent antifouling properties and could be used to separate oil/water mixtures continuously for up to 12 h without any increase in the...

The separation of chiral transformation products greatly complements the understanding of the stereochemistry of chiral pollutants. In this study, direct enantiomeric resolution of metalaxyl and its main degradation product metalaxyl acid, often co-occurring in the environment, was carried out in normal-phase high-performance liquid chromatography with a Chiralcel OJ-H column. (R)-Metalaxyl aci...

Water contaminated by oil and gas production poses challenges to the management of America's water resources. Here we report the design, fabrication, and laboratory evaluation of multi-walled carbon nanotubes decorated with superparamagnetic iron-oxide nanoparticles (SPIONs) for oil-water separation. As revealed by confocal laser-scanning fluorescence microscopy, the magnetic carbon nanotubes (...

Abstract Foamed materials are honeycomb-shaped structures bearing porous networks which exhibit considerable compressive strengths, and excellent efficiency for oil-water separation. The presence of spilled oils solvents in wastewater intensifies with accumulation over the time later creating toxicity to environment. ever growing industrial demands precede contamination water sources make it di...
