Open Access Articles | Treatment of Methylene Blue and Methyl Orange Dyes in Wastewater by Grafted Titania Pillared Clay Membranes

Author(s): Nalini Neethu, Tanushree Choudhury*.

 

 

 

Abstract:

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.

Most Cited Article : “Nanostructured Zinc Oxide for Water Treatment”

Nanoscience & Nanotechnology-Asia

Author(s): Sunandan Baruah, Samir K. Pal and Joydeep Dutta

nanoscience and nanotechnology2Abstract: Environmental pollution and industrialization on a global scale have drawn attention to the vital need for developing new hygienically friendly purification technologies. Existing wastewater treatment technologies demand high capital investment and operation & maintenance cost, and large area. Cost-effective treatment of pollutants requires the transformation of hazardous substances into benign forms and the subsequent development of effective risk management strategies from harmful effects of pollutants that are highly toxic, persistent, and difficult to treat. Application of nanotechnology that results in improved water treatment options might include removal of the finest contaminants from water (< 300 nm) and “smart materials” or “reactive surface coatings” with engineered specificity to a certain pollutant that destroy, transform or immobilize toxic compounds.

Article Title: Preparation of Novel Isotropic Pitch with High Softening Point and Solvent Solubility for Pitch-based Electrospun Carbon Nanofiber

Author(s): Byung-Jun Kim, Hyunsig Kil, Naoki Watanabe, Min-Hyun Seo, Bo-Hye Kim, Kap Seung Yang, Osamu Kato, Jin Miyawaki, Isao Mochida and Seong-Ho Yoon

Abstract:

The novel isotropic pitch that exhibits both high solvent solubility (100% soluble in THF) and a high softening point (over 200°C) was successfully synthesized by the bromination of 2-methylnaphthalene followed by dehydrobromination/polymerization and extraction in n-hexane to eliminate lighter constituents. The molecular structure of the pitch was relatively linear with flexible methylene cross-linkages between naphthalene molecules. During bromination, a reaction temperature of 180°C was necessary to induce bromine substitution of methyl hydrogen. Methylene cross-linkages were formed after the dehydrobromination reaction. The obtained pitch is a suitable precursor for electrospinning and meltspinning to prepare carbon nanofibers and carbon fibers, respectively.

Article Title: Production and Purification of Functional Lipids Through Enzymatic and Microorganism-Mediated Processes

Author(s): Toshihiro Nagao, Yomi Watanabe, Hirofumi Nakano and Yuji Shimada

Abstract:

The most remarkable difference between a chemical reaction and a lipase reaction is the fact that lipase possesses several substrate specificities, in particular, fatty acid specificity on hydrolysis, esterification, or transesterification reaction of the ester bond. Several lipases act weakly on polyunsaturated fatty acids (PUFAs) such as docosahexaenoic acid (DHA) and arachidonic acid. Through fatty acid specificity of lipases, a DHA-rich oil (acylglycerols) has been industrially produced from tuna oil. Lipase specificity also facilitates purification of PUFAs, conjugated linoleic acid isomers, tocopherols, and sterol esters and production of triacylglycerol that is DHA– rich at the sn– 1(3) position. Microorganism-mediated processes using Aeromonas hydrophila N– 6 are effective for production of rare unsaturated fatty acids and rare unsaturated fatty alcohols from several vegetable oils. These lipids are rarely observed in natural oils. We also demonstrate that Acinetobacter sp. N– 476– 2 effectively converts functional arachidonic acid to functional arachidonyl alcohol, which can be used as a substrate for medicine.

Article Title: Selective Photocatalytic Oxidation Of Benzyl Amine By O2 Into N-Benzylidenebenzylamine on Tio2 Using Visible Light

Author(s): Shinya Higashimoto, Yoshiaki Hatada, Ryo Ishikawa, Masashi Azuma, Yoshihisa Sakata and Hisayoshi Kobayashi

Abstract:

This paper deals with the photocatalytic oxidation of benzyl amine by O2 on TiO2 under visible light irradiation, and it was found that the benzyl amine is selectively converted into N-benzylidenebenzylamine with high conversion (>80 %). The origin of visible light response is not due to the band-gap transition of TiO2, but to the excitation of the charge transfer surface complex constructed by the interaction of benzyl amine with the TiO2 surface, as characterized by spectroscopic analysis such as UV-Vis, FT-IR and DFT calculations. Moreover, investigations of the role of the surface OH groups on TiO2, the electron-transfer from the surface complex as well as kinetic studies provided insight into the reaction mechanisms.
Article Title: Photocatalytic Reduction of Carbon Dioxide over Shape-Controlled Titanium(IV) Oxide Nanoparticles with Co-catalyst Loading
Author(s): Naoya Murakami, Daisuke Saruwatari, Toshiki Tsubota and Teruhisa Ohno
Abstract:

Photocatalytic reduction of carbon dioxide (CO2) was carried out using titanium(IV) oxide (TiO2). Methanol (CH3OH) was detected as the main product, and trace amounts of formic acid, carbon monoxide, methane, and hydrogen were also detected. The prepared decahedral-shaped anatase TiO2 with larger {011} and smaller {001} exposed crystal faces showed larger CH3OH generation than that of commercial anatase TiO2 powder, ST-01 (Ishihara Sangyo Co.). Photodeposition of silver and gold nanoparticles on the decahedral-shaped anatase TiO2 induced an increase in CH3OH production because the deposited metal particles work as reductive sites for multi-electron reduction of CO2.
