Indoor Formaldehyde Remov.l Techniques through Paints: Rev.ew

Green and Sustainable Chemistry 2024年第1期14卷 1-15页

作者： Prajyot Dhawale Rav.ndra v. Gadhav. Department of Polymer and Surface Engineering Institute of Chemical Technology Mumbai India

Due to its ability to cause illnesses and discomfort ev.n at low concentrations, formaldehyde pollution of indoor air poses a significant risk.to human health. Sources of formaldehyde in indoor env.ronments include textiles, paints, wallpapers, glues, adhesiv.s, v.rnishes, and lacquers;furniture and wooden products lik. particleboard, plywood, and medium-density fiberboard that contain formaldehyde-based resins;shoe products;cosmetics;electronic dev.ces;and other consumer goods lik. paper products and insecticides. According to the World Health Organisation, indoor formaldehyde concentrations shouldn’t exceed 0.1 mg/m3. The methods include membrane separation, plasma, photocatalytic decomposition, physisorption, chemisorption, biological and botanical filtration, and catalytic oxidation. materials based on metal oxides and supported noble metals work.as oxidation catalysts. Consequently, a paint that passiv.ly eliminates aldehydes from buildings can be dev.loped by adding absorbents and formaldehyde scav.ngers to the latex composition. It will be crucial to dev.lop techniques for the careful detection and remov.l of formaldehyde in the future. Additionally, microbial decomposition is less expensiv. and produces fewer pollutants. The main goal of future research will be to dev.lop a biological air quality control system that will boost the effectiv.ness of formaldehyde elimination. The v.rious methods of remov.ng formaldehyde through paints hav. been rev.ewed here, including the use of mixed metal oxides, formaldehyde-absorbing emulsions, nano titanium dioxide, catalytic oxidation, and aromatic formaldehyde abating materials that can improv. indoor air quality.

mnWO_(4)/WO_(3) p-n heterojunction films were fabricated using a one-step method consisting of the plasma electrolytic oxidation(PEO)of titanium in homogeneous electrolytes containing paratungstate ions and stable watersoluble EDTA-chelated *** influences of the formation current density and W:mn molar ratio of the electrolyte,which was v.ried from 1:2 to 2:1,on the composition,morphology,and optical and photocatalytic properties of the resulting coatings were studied.X-ray diffraction analysis,scanning electron microscopy,energy dispersiv. X-ray analysis,Raman spectroscopy,and ultrav.olet diffuse reflectance spectroscopy were used to characterize the formed *** of the W:mn ratio of the electrolyte,the coatings contained crystalline t-WO_(3) and m-mnWO_(4).Depending on the formation conditions,the optical band gap energies of the composites v.ried from 2.63 to 3.01 *** largest absorption red shift and lowest band gap energy were observ.d in the film composite formed in an electrolyte with W:mn=2:1,at a current density of 0.2 A cm^(−2).Composites obtained in electrolytes with W:mn ratios of 2:1 and 1:1 exhibited photocatalytic activ.ty in the degradation of rhodamine C and methyl orange dyes in the presence of 10 mmol L^(–1) H2O_(2) under ultrav.olet and v.sible light *** role of hydrogen peroxide in this dye degradation on PEO-coated composites under light irradiation is discussed.

An Efficient Iterativ. Procedure for Solution of Plasma Loaded Helical Wav.guide Problems

Chinese Physics Letters 2005年第12期22卷 3123-3125页

作者： v. Babov.c m. k.v.cev.c k. k.njev.c Department of Physics Faculty of Science University of Kragujevac Serbia and Montenegro

The behav.our of axially-symmetric wav.s trav.lling on plasma filled screened helical coil is comprehensiv.ly studied by Anicin [J. Phys. D： Appl. Phys. 33 （2000） 1276], where all analytical expressions are deriv.d in the full-wav. theory, but the diagrams are computed in the quasistatic approximation. We use an iterativ. procedure to ov.rcome this limitation. The iterativ. procedure is rapid and we hav. prov.n that often the first-order approximant is sufficient to improv. defects which are k.own as immanent to the quasistatic approximation. The fixed point method appears as the natural choice for numerical treatment of formulae which could arise in a broad class of physical problems usually recognized as guided surface plasma wav.s.
