GB/T 8151.3-2012 《Methods for chemical analysis of zinc concentrates - Part 3： Determination of iron content - Na2EDTA titrimetric method》 Related products
This standard specifies a method for the determination of iron content in zinc concentrates, which is applicable to the determination range of 2.00% 20.00% of iron content. After dissolving the sample at low temperature with muriatic acid and nitric acid, evaporate to nearly dry, add water and ammonia to settle iron. Using sulfosalicylic acid as an indicator, titrate with Na2EDTA standard titration solution in the range of 50 ° C90 ° C until the solution Color changes from red to yellow to determine the iron content. This method ensures the accurate determination of iron content in zinc concentrates.
