Background and purpose: Textile dye effluents have some potential risks which require effective treatment before discharging into the environment. Advanced oxidation processes can remove pollutants faster than other processes due to active hydroxyl radical production; therefore, increase the efficiency of dye removal. This study was aimed at investigating dye removal process using UVA/ZnO and U...
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...
background and purpose:organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. the aim was to evaluate the performance nanoscalezero-valent iron (nzvi) in the removal of dye acid red 18 (ar18) from aqueous solutions. materia...
A readily accessible (less than four synthetic steps) dye molecule with potential properties well-beyond the current state-of-the-art for use in dye-sensitized solar cells (DSCs) is realized from extensive quantum chemical...
Synthetic dyes are integral part of many industrial products. The effluents generated from textile dyeing units create major environmental problems and issues both in public and textile units. Industrial wastewater treatment is one of the major problems in the present scenario. Though, the physical and chemical methods offer some solutions to the problems, it is not affordable by the unit opera...
Abstract Introduction: Textile industry is regarded as one of the largest producers of dye and organic compounds, and Methylene Blue is the most commonly used dye material. In the present study, peanut shell powder was used as a low-cost adsorbent for removal of Methylene blue dye from aqueous solutions. Methods: In this experimental study, effect of operating parameters including pH ...
Background: Dye and colored materials cause health risks in water and therefore, must be removed from water supplies and wastewater. The aim of this study was to evaluate the effectiveness of the third generation poly(amidoamine) (PAMAM) and poly (propylene imine) dendrimers (PPI-G3) in the removal of reactive blue 19 (RB19) dye from aqueous solutions and determine the optimum conditions for t...
Synthetic dyes released by various industries pose a real concern to the environmental safety. Existing physico-chemical methods of dye removal from effluents suffer from severe constraints like low efficiency, high operational cost and large amount of sludge generation. Over the last two decades, considerable work has been done with the goal of using microorganisms as bioremediation agents in ...
Synthetic dyes are extensively used in many industrial applications like textile, leather and cosmetics. The release of various harmful dyes from these industries into the environment has attracted great attention worldwide in recent years. Biosorption is a very effective dye removal technique from aqueous system. In this research, the biosorption performance of cone of red pine for C.I. Basic ...
