【摘要】 以硫化银—硫化铅陶瓷膜为离子载体的铅离子化学传感器对Ｐｂ２＋ 具有很高的灵敏度和选择性，Ｐｂ２＋ 的浓度低到１０－６ｍｏｌ／Ｌ时也呈现Ｎｅｒｎｓｔ 响应；通过标准添加或电势滴定操作，该传感器可应用于陶瓷工业的环保检测和陶瓷材料中的铅、钛、铝及硫酸根的测定。更多还原

【Abstract】 Lead ion chemical sensor with Ag 2S-PbS-Ceramic mambrance as the carrier has high sensitivity and selectivity to Pb 2+ .Nernst response is showed as low as 10 -6 mol/L of the ion.It can be applied for determination of lead, titanium, aluminium and sulphate in ceramic materials by the standard-addition method or the potentiometric titration.更多还原
