Calculation of Accumulative Stabilization Constant and Chemical Speciations of Lead by Artificial Neural Network

Mo Hua, Deng Bo (Department of Chemistry, Tsinghua University, Beijing, 100084)  
Linear Feedforward Neural Network model is used to calculate the Accumulative Stabilization Constants between Pb 2+ and OH - by three different algorithms.Using the data obtained,the concentrations of different chemical speciations in aqueous solution for Pb 2+ and simulation curve of ΔE p change with pH are calculated using the feedback Neural Network.It shows that the measuring errors and CO 2- 3 within 4pH9 have great effect on the results of simulation while effect of the temperature can be omitted within the experimental error.
