General method for determination of chloride content in inorganic chemical products Mercury titration and ion chromatography Warning. Some of the reagents used in this document are hazardous and should be used with caution. Personnel using this document should have formal laboratory experience. This document does not address all possible safety issues and it is the user's responsibility to take appropriate safety and health measures. and ensure that the conditions stipulated by relevant national laws and regulations are met.1 ScopeThis document provides the general provisions, reagents or materials, instruments and methods for the determination of chloride content in inorganic chemical products using the mercury titration method and ion chromatography method. The principle, test steps and test data processing of mercury titration and ion chromatography for the determination of chloride content in inorganic chemical products are described. process, as well as precision and recovery. This document is applicable to the determination of chloride content in inorganic chemical products by mercury titration and ion chromatography. For samples with a mercuric nitrate content of 0.01 mg to 80 mg, when the concentration of the mercuric nitrate standard solution is less than 0.02 mol/L, titrate in ethanol. The determination range (mass fraction) of ion chromatography is 0.0001%~1%.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.
