GB/T 8151.17-2012 《Methods for chemical analysis of zinc concentrates - Part 17：Determination of zinc content - Hydroxide precipitation and Na2EDTA titrimetric method》 Related products

GB/T 8151.17-2012 For zinc concentrates, the zinc content is determined by the hydroxide settling-Na ² EDTA Titrimetric method. This standard is applicable to all kinds of zinc concentrate samples. First, the interfering elements are separated by the hydroxide settling, so that the zinc is separated from the impurities in the form of hydroxide settling, and then the settling dissolves, and the zinc ions are titrated with Na ² EDTA standard solution. The standard specifies the requirements of Burette and other instruments, and specifies the preparation method of reagents. Detailed description of the Sample Handling process, including sample analysis, settling operation and subsequent titration links. Standardize the entire operation process, and the zinc content of zinc concentrate can be accurately determined according to this standard, providing key data for the mass control of zinc concentrate and related production.
