Rotatable central composite design versus artificial neural network for modeling biosorption of Cr⁶⁺ by the immobilized Pseudomonas alcaliphila NEWG-2.

ABSTRACT: Heavy metals, including chromium, are associated with developed industrialization and technological processes, causing imbalanced ecosystems and severe health concerns. The current study is of supreme priority because there is no previous work that dealt with the modeling of the optimization of the biosorption process by the immobilized cells. The significant parameters (immobilized bacterial cells, contact time, and initial Cr⁶⁺ concentrations), affecting Cr⁶⁺ biosorption by immobilized Pseudomonas alcaliphila, was verified, using the Plackett-Burman matrix. For modeling the maximization of Cr⁶⁺ biosorption, a comparative approach was created between rotatable central composite design (RCCD) and artificial neural network (ANN) to choose the most fitted mod
