Talyzin*a The change of distance between individual graphene oxide sheets due to swelling is the key parameter to explain and predict permeation of multilayered graphene oxide (GO) membranes by various solvents and solutions. first proposed the use of graphene oxide (GO) as a highly effective fluid loss control agent for water-based drilling fluids. To explore the possible application of graphene oxide (GO) as a suitable adsorbent for the removal of U(VI) in solutions, sorption of uranium on GO was investigated as a function of pH, ionic strength, foreign ions and U(VI) concentrations using a batch technique. A novel carboxymethyl cellulose (CMC)-supported graphene oxide aerogel (CGOA) was fabricated from a cost-effective and abundant bituminous coal by a mild hydrothermal process and freeze-drying treatment. Newsfile Corp., Newsfile • June 11, 2020. Introduction. 1,2,3 Interest in GO increased dramatically after graphene, a single layer of graphite, was first isolated and studied. The structure of RGO-HA was confirmed using various characterization techniques. The effects of ultrasound power, ultrasound pulse mode, reaction temperature, pH value and L-AA amount on … Graphene oxide (GO, product numbers 763705 and 777676) is a unique material that can be viewed as a single monomolecular layer of graphite with various oxygen containing functionalities such as epoxide, carbonyl, carboxyl and hydroxyl groups. As a kind of earth-abundant and cheap natural clay mineral, palygorskite (Pal) was facilely modified by grafting with graphene oxide (GO) to fabricate GO/Pal composites for rapid removal of Pb(II) from aqueous solutions. T1 - Structure of graphene oxide membranes in solvents and solutions. Team; Corporate Social Responsability; Products. Bloomberg the Company & Its Products The Company & its Products Bloomberg Terminal Demo Request Bloomberg Anywhere Remote Login Bloomberg Anywhere Login Bloomberg Customer Support Customer Support Due to a variety of oxygen functionalities, GO can be well dispersed in aqueous solutions but unstable in the presence of alkaline cementitious solutions, which restricts the fully utilization of GO to the mechanical enhancement of cementitious materials. The reduction of graphene oxide (GO) to graphene (rGO) was achieved by using 20 kHz ultrasound in L-ascorbic acid (L-AA, reducing agent) aqueous solutions under various experimental conditions. In this study, graphene oxide was used as a nanostructured adsorbent with properties supposedly better than other common adsorbents to remove 4-chlorophenol from aqueous solutions. AU - Yu, Junchun. Hexylamine (HA) functionalized reduced graphene oxide (RGO-HA) was prepared via the modification of graphene oxide (GO) with HA, followed by reduction with hydrazine hydrate. TY - JOUR.
