industrial wastewater included the dyes one of the important sources of environmental pollution that founded in loom wastewater which are harmful for human health and environment. therefore, the purpose of this research was investigated removal of rb5 dye from aqueous solution by using of adsorption onto activated red mud as an cheap adsorbent. this research was experimental- laboratorial study...
background textile dyes are the largest organic compounds associated with some problems for the environment. advanced oxidation process is the most effective method for dye removal from wastewater. objectives the aim of this study was to investigate the efficiency of the photo fenton process for decolorization of direct red 81 (dr 81) dye, and to determine the optimal process conditions. method...
Removal of a cationic dye – Basic Red 12 – from aqueous solution by adsorption onto animal bone meal
Introduction: The dye wastewaters of textile industries are often toxic and persistent in the environment. In previous years, various methods are considerate in the removal of reactive dyes. Reactive red 198 dye is one of the mono azo dyes that is now used in textile industries. The aim of this study was to investigate the efficiency of Russian Knapweed Flower powder in the removal of reactive ...
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 ...
background: colors make many problems and these are major sources of environmental pollution. therefore, this wastewater should be treated before discharge to environment to reduce the environmental threats. adsorption is one of the usual processes for color removal from wastewater. nanotube s are new adsorbents with extend application for adsorption of different compounds. aim of this study wa...
conclusions the uv/zno system has been found an effective process with 90.2% cod removal and 95.6% dye removal after 50 minutes treatment. materials and methods in this work, zno catalyst and mercury lamp (uv-c, 254 nm) have been applied for removal of the c.i. sulphur red 14 dye from aqueous environments. the influence of various parameters such as the amount of zno, initial dye concentration,...
in this work, removal of c. i. acid red 14 was investigated by pumice stone as a low cost adsorbent. various parameters such as initial dye solution, contact time and ph were studied. removal of dye were increased by increasing of contact time and initial dye solution and deceased by increasing of ph. three isotherm models were studied. linear and non-linear regression analyses were used for de...
In this work, the ability of the MgCaFe- Layered double hydroxide (LDH) for congo red (CR) dye removal in aqueous solution was investigated. Various parameters such as initial dye concentrations, temperature, adsorbent dosage, pH effect and agitation rate were examined and optimal conditions (10 mgL-1 of the dye concentration, 25 °C of temperature, 0.5 gL-1 of the adsorbent dosage, pH~7 and 450...
