As a well-known one-atom thick nanosheets with preeminent physicochemical properties, graphene and its derivatives (e.g., graphene oxide, GO) have shown great potential on the membrane separation filed. This paper presents an update of GO laminates developments, including the membrane preparation methods, physicochemical properties and water vapor transport of GO laminates, and their applicatio...

A method for the analysis of several volatiles compounds responsible for orange juice flavour (ethyl butanoate, limonene, linalool, alpha-pinene, geranial, neral and alpha-terpineol) has been developed. The isolation of this compounds was carried out by pervaporation (PV) followed by on-line gas chromatography-mass spectrometry (GC-MS). The coupling PV-GC-MS has been successfully applied to fre...

Membrane technology for the processing of fruit juices and beverages has been applied mainly for clarification using ultrafiltration and microfiltration, and for concentration using reverse osmosis. The effects of product preparation, membrane selection, and operating parameters are important factors influencing filtration rate and product quality. Technological advances related to the developm...
