The accelerated sonophotocatalytic degradation of Reactive Red (RR) 120 dye under visible light using dye sensitized TiO2 activated by ultrasound has been carried out. The effect of sonolysis, photocatalysis and sonophotocatalysis under visible light has been examined to study the influence on the degradation rates by varying the initial substrate concentration, pH and catalyst loading to ascer...
International Shadegan wetland is the one of large Iranian wetlands. This wetland is located in south west Iran in Khuzestan province. Dams construction and not observing of wetland water needs, breeding fish, Saccharum industry sewages, oil pipes crossing, activity of 30 petrochemical unit and urban wastes discharge, entered this unique wetland, from 1992 in red list of international wetlands ...
The AgBr loaded TiO2 catalyst was prepared by a feasible approach with AgBr and tetraisopropyl orthotitanate and characterized by BET surface area measurement, diffuse reflectance spectra (DRS), scanning electron microscope (SEM), energy dispersive spectra (EDS), X-ray diffraction (XRD), transmission electron microscope (TEM) and atomic force microscope (AFM) analysis. The results of characteri...
background; conventional chemical coagulation is considered as the old method to color and cod removal in textile effluent. electrocoagulation (ec) process is a robust method to achieve maximum removal. methods; this work was designed to compare the result of operational parameters including optimum ph and coagulant concentration for chemical coagulation with ferric chloride and alum. also, the...
conclusions while the crp value was in patients with acute brucellosis in the current study, the mpv, rdw and leukocyte counts were within the normal range. crp value remains the most valuable inflammatory marker in cases of acute brucellosis. results the follow-up within the year after treatment was examined. the values of age, gender, leukocyte count, c-reactive protein, rdw and mpv were reco...
Background and purpose: Adsorption processes are widely used in removing pollutants from waste waters, particularly those that are not easily biodegradable such as dyes. In this study natural zeolite, which is easily found in many places, was used as a low-cost adsorbent for removal of dye from effluents. Materials and methods: Adsorption of Azo dyes including two basic and one reactive (React...
Abstract Fabricating surface oxygen vacancies is considered to be an efficient method improve the adsorption performance of sorbents. In this work, a bismuth oxychloride/biochar (BiOCl/BC) nanocomposite with abundant was successfully prepared by facile ball milling method. BiOCl/BC found have excellent for removing reactive red-120 (RR120) from aqueous solution. The effects key parameters, such...
background: recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. reactive dyes are widely used in textile industry. advanced oxidation processes are one of the cost-effective methods for the removal of these dyes. the main aims of this study were determining the feasibility of...
abstract introduction: dyes are among the most hazardous chemicals in industrial wastesdue to their toxicity for aquaculture, reduction of light permeability, and in turn development of disorders in photosynthesis process. the current study aimed to investigate the efficiency of coral in removing red reactive 198 from textile dye wastewater was investigated. materials & methods: in this experim...
