Laminated graphene oxide membrane for recovery of mercury-containing wastewater by pervaporation

Fabrication of ultrathin graphene oxide-coated membrane with hydrophilic properties for arsenate removal from water

Terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. This study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (GO) thin layer to remove arsenic (v) from water. To fabri...

Thin film nanocomposite forward osmosis membrane prepared by graphene oxide embedded PSf substrate

One of the limiting factors in good performance of forward osmosis (FO) membranes is the internal concentration polarization (ICP). To reduce ICP, thin film nanocomposite forward osmosis (TFN-FO) membranes were fabricated by adding different amounts of graphene oxide (GO) nanoplates (0-1 wt. %) to polymer matrix of polysulfone (PSf) substrate. The prepared nanocomposite membranes exhibited both...

Fabrication of graphene oxide composite membranes and their application for pervaporation dehydration of butanol

Pervaporation: Membrane Separations

G-100 is used for higher molecular mass proteins. The solutions of proteins are prepared in guanidine hydrochloride (10 mg mL ), and cytochromec (10 mg mL ) is used as an internal standard. Descending chromatography is carried out at room temperature under an inclination angle of 253 to the horizontal. After 3 h of development the quotient Rs protein/Rs cytochrome c is calculated for each prote...

Antibacterial activity of graphite, graphite oxide, graphene oxide, and reduced graphene oxide: membrane and oxidative stress.

Health and environmental impacts of graphene-based materials need to be thoroughly evaluated before their potential applications. Graphene has strong cytotoxicity toward bacteria. To better understand its antimicrobial mechanism, we compared the antibacterial activity of four types of graphene-based materials (graphite (Gt), graphite oxide (GtO), graphene oxide (GO), and reduced graphene oxide ...
