Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 25956-17-6, is researched, Molecular C18H14N2Na2O8S2, about Modeling of fixed-bed dye adsorption using response surface methodology and artificial neural network, the main research direction is modeling fixed bed polyurethane chitosan foam adsorption red dye; artificial neural network modeling dye foam adsorption red dye; response surface methodol modeling red 40 dye adsorption; adsorption wastewater treatment red 40 dye polyurethane chitosan foam.Recommanded Product: Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate.
Artificial neural network (ANN) and response surface methodol. (RSM) models were used to analyze the fixed bed adsorption of food, drug, and cosmetic (FD&C) red 40 dye by polyurethane/chitosan foam (PU/CS foam). The adsorbent was prepared and characterized. The effect of process variables (flow rate, bed height) were examined on two levels by RSM. Break-through curves were used as a training dataset for ANN. ANN was customized with 10 neurons in the hidden layer using the hyperbolic tangent sigmoid transfer function as activation function and the linear transfer function in the output layer. The optimal range of bed operation was 5-6 cm bed height and 15-17.05 mL/min flow rate. Column exptl. adsorption capacity values were 44.3-108.1 mg/g, and were compared with ANN and RSM modeling results. ANN predicted exptl. data with greater accuracy than RSM. Coefficient of determination values were 0.9911 for ANN and 0.8853 for RSM. Various error functions tested for ANN and RSM model-predicted and exptl. values demonstrated the better applicability and efficiency of the ANN model. PU/CS foam proved a promising, low cost adsorbent with excellent potential to remove FD&C red 40.
