Specifies a lead sulfate precipitation EDTA titrimetric method for the determination of lead content in lead sulfide concentrates. Applicable to all lead sulfide concentrates with lead content in the range from 10 % (m/m) to 80 % (m/m).
Abstract
Overview
ISO 11441:1995 specifies a titrimetric analytical procedure for the determination of lead content in . The method is based on precipitation of lead as , dissolution of that precipitate in a known volume of (disodium ethylenediaminetetraacetic acid) and of the excess EDTA with a standardized solution. It applies to concentrates with lead contents from and includes sample preparation, reagents, apparatus and calculation rules.
