TL;DR: In this article, it was shown that it is impossible and inappropriate to approximate the Langmuir-Hinshelwood kinetics to zero-order kinetics, and therefore, it is not possible to approximate it to zero order kinetics.

TL;DR: The present study showed that the size of the error function alone is not a deciding factor to choose the optimum isotherm, and the theory behind the predicted isotherms should be verified with the help of experimental data while selecting the optimumIsotherm.

TL;DR: A three-layer feed-forward neural network was constructed and tested to analyze the kinetic dye uptake of a batch activated carbon adsorption process and was found to be precise in modeling the rate of dye uptake for the operating conditions studied.
Abstract: A three-layer feed-forward neural network was constructed and tested to analyze the kinetic dye uptake of a batch activated carbon adsorption process. The operating variables studied are the contact time, initial dye concentration, agitation speed, temperature, initial solution pH, activated carbon mass, and volume of the dye solution treated. The studied operating variables were used as the input to the constructed neural network to predict the dye uptake at any time as the output or the target. The constructed network was found to be precise in modeling the rate of dye uptake for the operating conditions studied. The constructed neural network was found to be highly precise in predicting the dye uptake rate for the new input data, which are kept unaware of the trained neural network showing its applicability to determine the reaction rate for any operating conditions.
