Background and purpose: In Electro/Fe2+/persulfate process, persulfate radicals are produced as powerful oxidizing agents which increase the efficiency of this process. The aim of this study was to investigate the efficiency removal of COD, TSS and dye from industrial effluent in Buali industrial area in Hamedan. Materials and methods: In this study, the batch experiment was performed using a ...
Electrospinning of nanofibers with cyclodextrin (CD) is attractive because the produced fibers can potentially increase the efficiency of nanofibrous membranes by facilitating the complex formation with organic compounds and high surface area of the nanofibers. In this work, polyacrylonitrile (PAN) nanofibers functionalized with β– cyclodextrin (βCD) during an electrospinning process were used ...
decolorization of remazol brilliant blue r (rbbr) by trametessp. pellets was studied in a batch reactor. dye removal process was performed in shaken flasks which contained 100 ml of rbbr aqueous solution and fungal pellets. the process was followed for 48 h and the dye removal was analyzed at a visible spectrum of 590 nm. response surface methodology (rsm) employing box behnken design at three ...
Background and purpose: Dyes from textile industry are amongst the major pollutants of the environment that are harmful for both human health and the environment. Azo dyes constitute the largest and the most important class of commercial dyes, accounting for 50% of all commercial dyes. This study investigated the efficacy of Cr-doped ZnO nanoparticles in removal of reactive black 5 (RB5) dye fr...
Direct Red 81, a dye widely used in textile industries, is frequently detected dye in water resources. High costs, the formation of hazardous byproducts, and high energy costs restrict the use of some removal methods. Therefore, the main objectives of this research are the feasibility of using soil containing iron as a low cost adsorbent to remove (Direct Red 81) from aqueo...
In this study, amine functionalized Kit-6 silica mesoporous magnetite nanocomposite (NH2-MMNC) was synthesized by chemical methods and used as an efficient and recoverable adsorbent for removal of Ponceau 4R, as a toxic dye, from aqueous solutions. The synthesized nanocomposites were characterized by XRD, FT-IR, BET and SEM instruments. The effect of various experimental parameters on the dye r...
Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was found that the increase of initial dye and H2O2 concentration and the increase of initial pH, are not beneficial for improving the dye removal efficiency. Increasing the dye con...
Background and Aim: In this study, the removal of dye blue reactive-171 by combination of advanced oxidation processes UV/H2O2 and SBAR has been investigated. Methods: The efficiency of chemical and biological system was first investigated separately. In chemical system, the kind, power, initial dye concentration and hydrogen parasitize and in biological system, hydraulic detention time, aerati...
Background and purpose: Çhemical dyes used in textile industries involve some potential risks including carcinogenic and mutagenic effects in human. Furthermore, penetration of different dyes into surface and groundwater is a source of color in water reservoirs. This study aims at investigating the removal efficiency of yellow 3 and disperse yellow 3 reactive dyes by combined ÇÂÇ-SBR system. ...
Background and purpose: Dyes and cyanide are the most important sources of environmental pollution, found in industrial wastewater, which are harmful for human health and environment. The purpose of this research was to investigate the Kinetic and efficiency of titanium dioxide photacatalytic process in removal of Reactive Black 5 (RB5) dye and cyanide from aquatic solution in a batch system....
