Investigation on the Adsorption of Reactive Red 141 Dye on Cloisite 20A Clay

The increasing amount of industrial wastes as a result of industrialization causes severe environmental problems and pollution. Pollution of clean water resources, which is one of the most fundamental requirements for living bodies, is one of the most important problems of our time. The treatment of textile waste water containing colored and toxic components is very difficult. In this work, the removal of colored substances from textile wastewater through the adsorption known as non-expensive and effective treatment method is targeted. For this aim, the adsorption behavior of Reactive Red 141 on a commercial organoclay, Cloisite 20A, was studied. Batch adsorption experiments were conducted to determine the adsorption kinetics and isotherm behavior of the dye. The used and unused adsorbent samples were subjected to FTIR and SEM analyses for characterization. The results of the experiments showed that the adsorption kinetics is independent of initial dye concentration whereas the percentage dye removal depends on the initial dye concentration
