摘要
文章研究了Pb(Ⅱ)-XO显色反应体系并用于铅离子浓度检测,该方法简便、选择性强、干扰因素少、灵敏度高。在波长570.1 nm下配合物的表观摩尔吸光系数为2.764×104 L·mol^(-1)·cm^(-1),铅离子浓度在0~2.5 ug/m L的范围内符合比耳定律,线性相关度达0.9995。可用于测定水样中铅含量。
A new method for the determination of Pb(Ⅱ) by its reaction With XO is reported. The apparent molar absorptivity is found to be 2.764×104L/(mol·cm) at 570.1 nm. Bear′s law is obeyed in the concentration range of 0.5 to 2.5 ug/m L of Pb(Ⅱ) of solution. The linear correlation coefficient reached 0.9995. This method has been applied to the determination of Pb(Ⅱ) in Water.
