摘要: 提出了交流示波计时电位法的人工神经网络校正方法,并对其可行性和适用性进行了探讨.用此方法分别解析了大量T1+存在时Pb2+和大量In3+存在时Cd2+的交流示波计时电位法的dE/dt-E曲线.结果表明,对Pb2+和Cd2+的预测最大相对误差不超过5%,其性能良好.

Abstract: Anew calibration method of A.C.oscillographic chronopotentiometry with artificial neural networks has been developed, and its feasibility and adaptability were discussed.This method was applied to the determination of Pb2+in excess of T1+, and Cd2+in excess of In3+system.The maximum relative error of Pb2+and Cd2+was not more than 5%.This study indicates that artificial neural networks may provide a new approach to determine the content for multi-component with A.C.oscillographic chronopotentiometry.
