Abstract :Langmuir isotherm model has been widely used by researchers in adsorption isotherm studies for more than a century. During the process, 6 linear equations have been derived from the Langmuir model, which is a non-linear model. This study focuses on these 6 equations which are rarely given together. In this study, the performance of clay mineral in the removal of a heavy metal known for its harmful effect, such as cadmium, from solution was measured. The data obtained as a result of adsorption of cadmium (II) ion with clay from Siirt Koçpınar region at a temperature of 298 K were applied to 6 linear equations derived from Langmuir isotherm model. As a result, it was determined that the degree of suitability of the models for adsorption was type 3= type 6 < type 1= type 4 < type 2 = type 5 and the most suitable R2 values belonged to type 2 and type 5 with values of 0.992. The largest qm value was found to belong to type 4 with a value of 86,608 gmg-1.
