“…In order to indicate the efficiency of the ionic liquid in increasing the surface area and nanocomposite pores, the efficiency of TiO 2 /graphene oxide prepared in the absence of ionic liquid toward Cd +2 and Pb +2 removal found to be 50% and 75%, respectively. Interestingly, the removal efficiency of the prepared nanocomposite toward cadmium and lead ions is promising and competitive with the previously published studies [43][44][45].…”

Ionic liquids attract attention in the last years due to its powerful solvation properties. For this reason, in current study 1-ethyl-3-methylimidazolium tetrafluoroborate [EMIM-BF 4 ] ILs was used for the synthesis of high surface TiO 2 /GO nanocomposite, as an active material for heavy metal removal from aqueous media. FT-IR, transmission electron microscopy (TEM), scanning electron microscope (SEM), and x-ray diffraction (XRD) techniques were employed for identification of the novel nanocomposite. Batch experiments were conducted for Cd +2 and Pb +2 uptake from wastewater by the synthesized nanocomposite. The effect of parameters affecting adsorption capicity, such as contact time, pH, nanocomposite dosage and the initial concentration of heavy metals were examined for Cd +2 and Pb +2 removal by the prepared nanocomposite. The removal efficiency of Cd +2 and Pb +2 was 69.36% and 89%, respectively, under optimal conditions confirming the ability to use the prepared nanocomposite for wastewater treatment from heavy metals with high efficiency.

“…Inorganic-organic hybrid materials with porous structure have more advantages on adsorption, and their adsorption properties have been applied widely in remove of environmental pollutants. For example, cobalt-trioctylamine inorganic-organic hybrid nanobelts showed excellent removal ability for the trace heavy metal ion Pb 2+ in wastewater [17]; Titania-silica-phosphonate triconstituent hybrid mesoporous materials was used as adsorbents both in gas and liquid phases [18]; among these inorganic-organic materials, CaCO 3 -organic polymer hybrid materials is very arrestive due to its controlled morphology and unique properties as well as being environmentally benign [19,20]. But it is till a challenge as regards their application potential.…”

“…degradation of emerging contaminants for its i) no neurological toxicity ii) high chemical stability in organic solvents and caustic soda iii) high material purity iv) small crystallite size v) low cost of crystalline anatase form vi) extreme stability vii) extreme amphoteric character and viii) wide band gap energy [7]. However, its performance requires further enhancement for treating diluted contaminants due to its small surface area and low adsorption ability [8, 9]. The separation of nanoscale titania photocatalyst from water is yet another problem to be solved for its widespread application of the process [10, 11].…”

Background: Amphoteric membranes such as Titania Pillared Clay (TiPILC) membranes exhibit different charges at different pH ranges, subsequently show efficient separation for cationic and anionic organic pollutants in wastewater based on solution pH. The structural properties of such membranes determine their permeability and selectivity to a large extent. The present work is initiated to explore the possibility of enhancing the surface area of TiPILC membranes by grafting with 3-aminopropyltriethoxysilane.Method: Grafted TiPILC membranes were fabricated by colloidal sol- gel route followed by dip coating, drying and sintering the membranes at 300oC. X-ray diffraction (XRD) spectra of the pillared photocatalyst membranes show the presence of only anatase phase, which exhibits better photocatalytic activity. Fourier Transform Infrared (FT-IR) spectra reveal the formation of delaminated TiPILC material. The specific surface area of TiPILC membrane obtained at pH3.5 is 183m2/g.Results: Literature survey of 47 papers was carried out for the work. 10 papers were based on patents being dealt on degradation of organic dyes in wastewater by conventional methods, though reports of membrane technology are limited in literature. The rest 37 papers outlined the importance of widespread use of titania photocatalyst powder for degradation studies.Conclusion: The membrane material thus developed is efficient in complete decolouration of both Methylene Blue and Methyl Orange dyes on account of the high surface charge and high surface area in just one cycle of filtration.
