Abstract



Coloring Materials are among the pollutants that must be removed from the waste water due to their carcinogenic effects. With adsorption, we can effectively and cheaply remove such contaminants. Adsorption is carried out using porous materials such as pumice, clay or activated carbon.In this study, it is aimed to remove Rhodamine B dye from waste water by using Van pumice. The samples were taken and applied to Freundlich and Langmuir isotherm models and the process was found to be compatible with the Freundlich isotherm model. In addition, thermodynamic parameters were calculated and it was calculated that the adsorption process was spontaneous and endothermic.
