Polyvinyl chloride supported silver molybdate composite material is used to develop by solution casting method. This membrane was characterized by various instrumental techniques such as Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) analyses. These characterizations are used to understand the functional groups,thermal sta...

The mechanical stability is an important phenomenon which governs many applications based properties of membranes. The inorganic materials of membrane may have been synthesized by qualitative the novel sol-gel or co-precipitation methods of material synthesis. The mMembranes of cobalt (CP) and nickel (NP) composites have been was designed by mixing of the polyvinyl chloride (PVC) with cobalt ph...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

In the present study, fabrication and characterization of compound composite nanofibers of Polyvinyl Alcohol (PVA) with nano silver and Polyamide 6 (PA6) are demonstrated. Compound composite fibers with core-shell structure were made using co-axial electrospinning method. The shell was made up of nano silver (Ag) impregnated PVA while PA6 was the core material. These compound composite nanofibe...

Biofilms can have deleterious effects on drinking water quality and may harbor pathogens. Experiments were conducted using 100 microg/liter silver to prevent biofilm formation in modified Robbins devices with polyvinyl chloride and stainless steel surfaces. No significant difference was observed on either surface between the silver treatment and the control.

traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. to design a membrane process for olefin-paraffin separation, equilibriu...

in this work, novel thin film composite membranes (tfcs) of poly (ether-6-block amide) (pebax-1657) on a polyvinyl chloride (pvc) ultrafiltration membrane as support were prepared using inclined coating method for co2 separation. investigating the effects of top selective layer thickness formed by controlling the coating angle (15-60°) and polymer solution concentration (5-10 wt.%), and also, t...
