Effectiveness of polyethylene glycol-coated silica on ions adsorption in industrial wastewater

Polyethylene glycol-coated biocompatible surfaces.

Surfaces covered with polyethylene glycol (PEG; HO-(CH(2)-CH(2)-O)(n)-H) have been shown to be biocompatible because PEG's properties yield nonimmunogenicity, nonantigenicity, and protein rejection. To produce a biocompatible surface coating, we have developed a method for grafting PEG onto activated silica films. We first deposited an amorphous silica film by plasma-enhanced chemical vapor dep...

Studying the Adsorption Behavior of Copper Ions in Industrial Wastewater, Using Modified Electrospun Polymeric Nano Fiber

Background & Aims of the Study:  Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Method...

Removal of Mercury (II) from Wastewater by Magnetic Solid Phase Extraction with Polyethylene Glycol (PEG)-Coated Fe3O4 Nanoparticles

   The presented study investigates application of polyethylene glycol (PEG)-coated Fe3O4 nanoparticles as an magnetic nanoadsorbent for magnetic solid-phase extraction (SPE) and the selective removal of toxic heavy metals such as mercury (II) from aqueous solutions and their determination using graphite furnace atomic absorption spectrometry (GF-AAS)...

Surface Adsorption of Polyethylene Glycol and Polyvinyl Alcohol with Variable Molecular Weights on Zinc Oxide Nanoparticles

Chitosan-polyethylene glycol coated cotton membranes for wound dressings

Membranes have been developed by coating a blend of chitosan (CS) and polyethylene glycol (PEG) of different molecular weights (4000, 10,000 and 20,000) on cotton fabric followed by freeze drying. The influence of PEG molecular weight on the physical characteristics of the membranes has been investigated. The scanning electron microscopy of the coated fabric reveals porous structure. The porosi...
