Reactive Blue 19 Dye Adsorption Behavior on Jujube Stems Powder from Syntetic Textile Wastewater: Isotherm and Kinetic Adsorption Studies
Introduction: Dyes have complicated structures, they are usually toxic and resistant to biological treatment and enter the environment through industrial waste streams. The aim of this study was to review the isotherm and kinetic adsorption studies of Reactive Blue 19 (RB19) dye onto Jujube stems powder from synthetic textile wastewater. Materials and Methods: This study was conducted in labo...

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولElectrochemical Degradation of Reactive Blue 19 Dye in Textile Wastewater
Textile wastewater is notoriously known to contain strong colour, a highly fluctuating pH and significant COD (Chemical Oxygen Demand) values. Because of these characteristics, treatment of these effluents has been rather difficult. Traditional methods for dealing with textile wastewater consist of various combinations of biological, physical and chemical methods. Because of the large variabili...
متن کاملImprovement of Photocatalytic Properties of Titanium Oxide Nanoparticles (TiO2) Doped with Cerium Atoms and Evaluation of Methylene Blue Dye and Wastewater antifreeze Treatment
In this study, the photocatalytic and bleaching properties of pure and doped titanium dioxide nanoparticles with 1%, 3%, 5% and 10% Ce dopant were studied using Ce(NO3)3 precursor. The results showed that the highest methylene blue degradation of the sample with 5% cerium impurity was 97% in neutral medium (pH=7) after 75 minutes. The bleaching response to wastewater treatment with 5% cerium im...
متن کاملDegradation of progestagens by oxidation with potassium permanganate in wastewater effluents
BACKGROUND This study investigated the oxidation of selected progestagenic steroid hormones by potassium permanganate at pH 6.0 and 8.0 in ultrapure water and wastewater effluents, using bench-scale assays. Second order rate constants for the reaction of potassium permanganate with progestagens (levonorgestrel, medroxyprogesterone, norethindrone and progesterone) was determined as a function of...
