| Abstract: | A mathematical model has been established through the general revolving combination design to describe the absorbance responses as a function of sodium lauryl sulfate, 4-(2-pyridylazo)-resorcinol, pH values of the system. After optimum coefficients were found for the model, the determination of Pb, Cd, Hg and Ni in unknown were complete by using B-P ANN. The study on B-P ANN and PLS showed that the results were satisfactory. |
