电位滴定法测定硫化铅精矿中铅含量

Determination of Lead Content in Lead Sulfide Concentrate by Potentiometric Titration

硫化铅是一种用途较为广泛的无机化合物,在陶瓷业、半导体工业以及金属铅的制备中用量非常大。为了更加准确地测定硫化铅精矿中的铅含量,主要就自动电位滴定仪配合铅离子选择电极测定硫化铅精矿中铅含量进行了探讨,通过实验可知,该方法既能得到准确度和精确度高的实验数据,又能消除人为误差,可以进行推广使用。

Lead sulfide is a widely used inorganic compound,which is widely used in the ceramic industry,semiconductor industry,and the preparation of lead metal.In order to more accurately determine the lead content in lead sulfide concentrate,this article mainly discusses the use of an automatic point titration instrument combined with a lead ion suspended electrode to determine the lead content in lead sulfide concentrate.Through experiments,it is known that this method can obtain experimental data with good accuracy and high precision,and can eliminate human errors,which can be promoted and used.
