GB/T 8152.1-2006 《Methods for chemical analysis of lead concentrates―Determination of lead content―EDTA titration method after acid digestion》 Related products

GB/T 8152.1-2006 The acid dissolve-EDTA Titrimetric method is used to determine the amount of lead in lead concentrates, which is suitable for all kinds of lead concentrates. First, the lead concentrate is dissolved with acid, so that lead ions enter the solution, and then the characteristics of EDTA complexation reaction with lead ions are used for titration analysis. The standard specifies the required instruments such as Burette, and clarifies the selection and preparation methods of reagents. The specific steps of acid dissolution of samples and the operation points in the titration process are described in detail, including titration speed, use of indicators and end point judgment. According to this standard, the lead content in lead concentrates can be accurately determined, providing important data support for mass control of lead concentrates and subsequent smelting processing.
