Directly applying an electric field on conductive membrane can effectively mitigate membrane fouling. Thus, a conductive reduced graphene oxide/polyvinylidene fluoride (RGO/PVDF) membrane was prepared by casting PVDF and graphene oxide (GO) solution over a selected carbon fiber cloth, then phase inversion and final heat treatment in hydroiodic acid (HI) solution. This method realized uniform and stable presence of RGO in PVDF membrane. Scanning electron microscopy (SEM) images showed addition of GO reduced the pore size of the composite membranes. The thermal HI treatment partially reduced graphene oxide to RGO, and made the membrane more conductive but less hydrophilic [as characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and contact angle (CA)]. From thermogravimetric analysis (TGA), it showed that the addition of GO and RGO improved the thermal stability of the membranes, when temperature was lower than 400 8C. The HI treatment increased the pore size and water flux of the RGO/PVDF membrane (being 71.6% higher than the GO/PVDF membrane). The RGO/PVDF membrane was used in separating polyacrylamide (PAM), a macromolecule pollutant in oil field waste water; when applying a 0.6 V/cm external electric field, its membrane fouling and flux decline was effectively slowed down, as shown in the fitting curves slopes using the classical cake filtration model (t/V-V). Being uniform and stable, the RGO/PVDF membrane had great potential for practical applications.

Acrylate Polymers for Advanced Applications

There are many polymers formed of acrylate monomers in existence. Here we interrogate four commonly-used examples and study how their solution properties are pH dependent, or how their state of ionisation can affect their solution properties. Poly(acrylic acid) and poly(methacrylic acid) are both polyelectrolytes, with ionisable functional groups that make them stimuli responsive, changing their hydrodynamic volume. Poly(acrylamide) is a mass-produced material used in a variety of industrial applications, often with an anionic and cationic co-monomer, which dictates both its efficacy and impact on the environment. Poly(N-isopropyl acrylamide) is a thermally responsive material with applications in smart bioengineering. In solution, these materials can interact with each other due to competing hydrogen bonding interactions. However, this interpolymer complexation is dependent on both the ionisation, and the conformational state, of the polymers involved. This review focuses on the results from fluorescence tagging and turbidimetric techniques.

“…Therefore, it is also important to develop an efficient way to remove HPAM from the aqueous phase and treat it adequately. Various studies have been conducted in this sense, both to remove HPAM from the aqueous phase (Lu & Wei, 2011;Cao et al, 2011;Liu et al, 2014) and to discharge it without contaminating the environment (Bao et al, 2010;Yongrui et al, 2015). Despite advances in research, Najamudin and colaborators (Najamudin et al, 2014) concluded that there is no appropriate offshore treatment so, for the studied field, the reinjection would be the best option.…”

The process of chemical enhanced oil recovery, CEOR, involves the injection of substances, such as polymers, that reach the production well after permeating the reservoir. These products affect the stability of the produced oily water after primary separation, making it harder to break down these oil-inwater emulsions. In an attempt to overcome this problem, researchers have studied the influence of polymers on the stability of oily water and have proposed the use of new equipments and chemical additives. This article reviews the studies of the influence of polymer flooding, the most used CEOR technique, on the stabilization and treatment of produced oily water. It is important to understand the influence of polymers on water treatment to avoid interrupting the production of oil and, more importantly, to prevent environment contamination.
