Adsorption is a unit operation of separating solute from solution using another solid material. Modelling experimental adsorption isotherm data an essential way for predicting the mechanisms adsorption, which will lead to improvement in science. The main aim present work analyse various forms Langmuir copper its aqueous cucumber peel batch data. linearized and nonlinearized models were compared discussed. In order determine best fit model, determination coefficient (R 2 ) sum square error (SSE) each model used. modelling results showed that nonlinear could better than other forms, with relatively higher R values (0.9879) smaller SSE (0.013). linear had maximum capacities deviated achieved was 66.61 mg/g after validation results.
