The potential feasibility of anionic clay hydrotalcite for removal of eriochrome black dye from aqueous solution was investigated. The effects of various experimental parameters such as contact time, pH and adsorbent dosage were investigated. The extent of eriochrome black dye removal increased with the increased in contact time, pH and amount of adsorbent used. Adsorption data was fitted to th...

as dyes are the most important pollutants of many industrial wastewaters. a large amount of reactive black 5 enters the environment in iran because of the use of this dye in iran's textile industries, so the goal of this study was to survey the catalytic ozonation process with bone char in removal of reactive black 5 dye from synthetic wastewater. in this experimental study bone char (bc) was p...

The arrays of artificial receptors were synthesized and used in the studies of binding of triphenylmethyl dyes. Rate of binding of Brilliant Black was determined by the measurements of decrease of optical density of dye solution. Considering the fast process of removing excess of dye and uniform coloration of receptors, Brilliant Black was evaluated as the most versatile reporter dye for Indica...

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...

a comparison of the photoefficiency of ni(ii) and nis incorporated into zeolite p towards photodecolorization of eriochrome black t dye solution was investigated in a photocatalytic reactor using uv lamp as a light source. the effect of various experimental variables on the decolorization performance of the process was evaluated by examining catalyst dosage, temperature, initial dye concentrati...
