| 摘 要： | 研究了以4－（2－吡啶偶氮）－间苯二酚（PAR）为显色剂、十二烷基硫酸钠（SDS）为增敏剂、乙酸－乙酸钠为缓冲液，在水相中对铅、镉、镍进行同时测定。利用二次回归正交组合设计，对体系因子进行了优化。以苏州吴县水稻田土壤为研究对象，利用反向人工神经网络对其中铅、镉、镍的全量、有效态、活化态分别进行了同时测定，预测结果与AAS法所测结果基本一致。

| Abstract: | In the presence of 4-(2-pyridinlazo)-resorcinol and sodium dodecyl sulfate, a spectrophotometric method for simultaneous determination of Pb, Cd, and Ni in environment samples was studied by back propagation artificied neural network(BP-ANN). The results were satisfactory. |
