“…The membrane permeate contained 0.3-0.43 mg/l of DOC (96-98% reduction), which were similar results to those obtained by Lynch and Smith [16]. More recently, Cho et al [17] studied the natural organic matter (NOM) rejection using ultrafiltration polyamide thin film composite (TFC) membranes (MWCO=8000 Da) as well as regenerated cellulose membranes (MWCO=3000 Da). It was shown that despite the large pores of UF membranes, the significant fractions of DOC were removed after membrane filtration, however, the degree of DOC removal was strongly affected by feed solution chemistry.…”

“…The occurrence of membrane fouling [3] is an inevitable problem. Membrane flux will gradually decrease with the increase of filtration time, and general clean water can not completely remove the oil drop plug in the membrane hole.…”

Abstract. We used cross-flow filtration method and made use of a certain degree of silicon carbide ceramic membrane at different filtration time, different operating temperature to treat with waste water so as to study the flux of membrane flux and the change of water quality and the amount of recoil cleaning on the recovery of membrane flux .The results show that: the silicon carbide ceramic membrane can effectively dispose the oily waste water. The energy consumption is lower and the membrane flux is stable, simultaneously, multiple recoil cleaning can also make the membrane flux fully recover when the filtration time is 15min, the membrane flux is large, the temperature is 35 degrees centigrade.

“…It has been reported that hydrophobic membranes can induce the adsorption of aromatic compounds (e.g. polycyclic aromatic hydrocarbons, humic substances, aromatic pesticides) onto the surface by hydrophobic and electrostatic interactions [161][162][163] and this fact has been used for the removal of organic pollutants during water treatment [162] .…”

Highlights Methodologies for fullerene aggregate characterization are discussed.  Chromatographic and electrophoretic techniques for fullerene analysis are presented.  Accurate identification and detection of fullerenes by LC-MS is critically reviewed. Graphical abstract AbstractA prominent sector of nanotechnology is occupied by a class of carbon-based nanoparticles known as fullerenes. Fullerene particle size and shape impact in how easily these particles are transported into and throughout the environment and living tissues. Currently, there is a lack of adequate methodology for their size and shape characterisation, identification and quantitative detection in environmental and biological samples. The most commonly used methods for their size measurements (aggregation, size distribution, shape, etc.), the effect of sampling and sample treatment on these characteristics and the analytical methods proposed for their determination in complex matrices are discussed in this review. For the characterisation and analysis of fullerenes in real samples, different analytical techniques including microscopy, spectroscopy, flow field-flow fractionation, electrophoresis, light scattering, liquid chromatography and mass spectrometry have been reported. The existing limitations and knowledge gaps in the use of these techniques are discussed and the necessity to hyphenate complementary ones for the accurate characterisation, identification and quantitation of these nanoparticles is highlighted.
