Neural Network Modeling and Simulation of Sorption of Cd (II) Ions from Waste Water using Agricultural Waste

A single-layer Artificial Neural Network (ANN) model was developed to predict the removal efficiency of Cd (II) ions from aqueous solution using saraca indica leaf powder (SILP). Batch experiments resulted into standardization of optimum conditions: biomass dosage (4.0 g), Cd (II) concentration (25 mg/l) volume (200 ml) at pH 6.5. A time of forty minutes was found sufficient to achieve the equilibrium. The ANN model was designed to predict sorption efficiency of SILP for target metal ion by combining back propagation (BP) with principal component analysis. A sigmoid axon was used as transfer function for input and output layers. The Levenberg-Marquardt Algorithm (LMA) was applied, giving a minimum mean squared error (MSE) for training and cross validation at the ninth place of decimal.
