Preparation of a graphene/silver hybrid membrane as a new nanofiltration membrane

A New Approach to Provide High Water Permeable Polyethersulfone based Nanofiltration Membrane by Air Plasma Treatment

In this study, polyethersulfone based nanofiltration membranes were modified by air plasma generated through dielectric barrier discharge to increase the membrane hydrophilicity aiming to improve the separation and antifouling characteristics. The effect of plasma time on the physico-chemical and separation properties of membrane was investigated. The PES nanofiltration membranes were fabricate...

Developing of Ethylene Glycol as a New Reducing Agent for Preparation of Pd-Ag/PSS Composite Membrane for Hydrogen Separation

In the present work, for the first time, a palladium-silver membrane has been prepared by electroless plating on the surface of a porous stainless steel disk by using ethylene glycol as a new reducing agent and polyol process. The reducing action of ethylene-glycol in the presence of PVP as a protecting surface agent produces a membrane with finely divided powder and nano-sized pores. Furthermo...

Application of Genetic Programming as a Powerful Tool for Modeling of Cellulose Acetate Membrane Preparation

Preparation of Polyvinylchloride Nanofiltration Membrane: Investigation the Effect of Thickness, Prior Evaporation Time and Addition Polyethylenglchol as Additive on Membrane Performance and Properties

In this work, polyvinylchloride (PVC) membrane prepared via casting solution technique and phase inversion method. N, N dimethylacetamide (DMAC) was used as primary solvent and Tetrahydrofuran (THF) was used as a co-solvent. The effects of parameters such as membrane thickness, evaporation time of casting film before immersion precipitation and addition of polyethylenglchol (PEG) on PVC membran...
