The equilibrium adsorption data were analyzed by Langmuir, Freundlich and Temkin adsorption isotherm models. The Langmuir and Freundlich adsorption models agree well with experimental data. The pseudo-second order, intraparticle intraparticle diffusion and Elovich kinetic models were applied to the experimental data in order to describe the removal mechanism of dye ions by waste marble dust. The pseudo-second order kinetic was the best fit kinetic model for the experimental data. Thermodynamics parameters such as Δ<em>G</em>, Δ<em>H</em> and Δ<em>S </em>were also calculated for the adsorption processes. The experimental data were used to construct an artificial neural network (ANN) model to predict removal of malachite green and acid blue 161 dyes by waste marble dust. A three-layer ANN, an input layer with four neurons, a hidden layer with 12 neurons, and an output layer with one neuron is constructed. Different training algorithms were tested on the model to obtain the proper weights and bias values for ANN model. The results show that waste marble dust is an efficient sorbent for malachite green dye and ANN network, which is easy to implement and is able to model the batch experimental system.</p> </div> <p> </p> </p></abstract><publication_date><month>05</month><day>28</day><year>2014</year></publication_date><pages><first_page>676</first_page><last_page>689</last_page></pages><publisher_item><identifier id_type="pii">gnest_01366</identifier></publisher_item><doi_data><doi>10.30955/gnj.001366</doi><timestamp>1714103768</timestamp><resource>https://journal.gnest.org/publication/gnest_01366</resource></doi_data></journal_article></journal></body></doi_batch> </div>
