Regression Analysis on Biosorption Study of Cu(II) by Dry Fruit Wastes
Keywords:Kinetic, isotherm, ground shells, linear method, non-linear method
A rigorous analysis based on linear and non-linear regression of various kinetic models (Pseudo First Order and Pseudo Second Order) and isotherm models (Freundlich, Langmuir, Tempkin, Duninin-Radushjevich, Brunauer-Emmett-Teller and Halsey) were examined to explore various aspects of Cu(II) biosorption onto ground shells of Almond (AS) and Walnut (WNS). Batch sorption studies were made at 30Â±2 ÂºC and 5 pH. The kinetic and isotherm parameters in case of Pseudo First Order, Pseudo Second Order and Langmuir linear equations are obtained from two, four and five linear equations respectively, but with the one non-linear individual method. Coefficient of determination (R2) was used to show the goodness of fit of a model. Sum of the square error (SSE) and root mean square error (RMSE) were also employed. Both biosorbents showed rapid removal of Cu(II) from synthetic solution and non-linear method found to be more appropriate method for obtaining parameters.
