Present study was performed to investigate the variables that influence the removal efficiency of malachite green (aniline) dye from aqueous solution by an electrochemical (EC) technique. The batch EC studies were performed using iron electrode to evaluate the effect of operating parameters such as pHo and processes parameters such as current density and initial dye concentration. Parameters pH...

Background: Conserving water for human survival and providing future security are important issues that need to be addressed. Methods: In this study, a zeolite modified with hexadecyl trimethyl ammonium bromide (HDTMA-Br), a cationic surfactant, and its application in removing direct blue 129 (DB129) was examined. Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy...

Background & Objectives: Cationic dyes such as basic violet have many applications in different industries. The degradation of basic violet by means of UV, UV/H2O2, US, and US/H2O2 processes was investigated. Materials and Methods: Photolysis process was accomplished in a laboratory-scale batch photoreactor equipped with a 55 W immersed-type low-pressure mercury vapor lamp (UVC) and sonolysis ...

The application of poly (vinyl alcohol) (PVA) in an unmodified form as an adsorbent for methylene blue (MB) dye removal in waste water at 303–333K was investigated. Effects of operational parameters such as adsorbent dosage, initial dye concentration and pH were determined for optimum conditions for maximum dye removal. Results obtained showed that dye removal efficiency increases as the amount...

MicrosoftInternetExplorer4 Background and Objectives: Synthetic dyes represent one of the largest groups of pollutants in wastewater of dying industries. Discharging these wastewaters into receiving streams not only affects the aesthetic but also reduces photosynthetic activity. Electrochemical advanced oxidation processes such as Electro-Fenton process are low operational and have high mi...

Introduction: Dyes are visible materials and are considered as one of the hazardous components that make up industrial waste. Therefore it is removed from bodies of water, using various methods. In this regard, the Fenton oxidation process is one of the most effective ways to remove colored contaminants in aquatic environments, which has many applications today. Materials and Methods: In this...

Different parameters were investigated to evaluate their effect on the process removal efficiency of reactive dye from simulated spent reactive dye bath, by solar / TiO2 / H2O2, including H2O2 concentration, TiO2 loading and pH. As a result 99% of reactive dye can be removed at a TiO2 loading of 400mg/l, H2O2 concentration of 150 mg/l and of pH: 5.2. The effect of photo-catalytic deactivation o...

Background and Objective: Existence of dye in water resources and wastewater can cause the environmental problems that must be removed from water. There has been some increase in the use of low-cost adsorbent substances as sewage treatment over recent years. Therefore, the purpose of this study was to optimize dye (RO16) removal from aqueous solutions by quarternary ammonium chloride (C6H15Cl2N...
