摘要
本文介绍了用微分脉冲伏安法以悬汞电极为工作电极测定铅(Ⅱ)-精氨酸及铅(Ⅱ)-丝氨酸络合物稳定常数。研究了仪器参数及实验条件对测定的影响,在20℃、离子强度为0.50M NaNO_3介质条件下,测得了铅(Ⅱ)-精氨酸及铅(Ⅱ)-丝氨酸络合物的累积稳定常数。
The effects of instrumental parameters and experimental conditions were sudied in the deter-mination of stability constants of lead (Ⅱ)-arginine and lead(Ⅱ)-serine complexes by differentialpulse voltammetry. The stability constants of the complexes were determined at 20℃ in solutionof 0.5 M NaNO_3 with satisfactory results.
