摘要: Artificial neural network (ANN) model was applied for predicting the biosorption capacity of excess municipal wastewater sludge hexavalent chromium (Cr(VI)) ions from aqueous solution. The effects initial concentration (5 to 90 mg/L), adsorbent dosage (2 10 g/L), pH 8), agitation speed (50 200 rpm) and time 480 min) were investigated. maximum amount removal about 96% in optimum conditions. experimental results simulated using ANN model. Levenberg-Marquardt algorithm used training this with tangent sigmoid as transfer function at hidden output layer 13 1 neurons, respectively. successfully predicted Cr(VI) capacity. average mean square error is 0.00401 correlation coefficient between rate 0.9833.
