GB/T 23840-2009 《Inorganic chemical products - General rules for potentiometric titration》 Related products
This standard specifies the instrumental requirements for the potential Titrimetric method of inorganic chemical products and general rules for quantitative analysis. It is applicable to acid-base titration, settling titration, oxidation-reduction titration and non-aqueous titration. It provides guidance especially for analytical methods for turbid, colored solutions and the lack of suitable indicators. The standard describes in detail the key terms in potential measurement, including the definitions of indicator electrode, reference electrode and derivative. The cited documents cover the specifications for analytical laboratory water, the preparation of standard titration solutions and the preparation of related chemical reagents. This standard ensures the accuracy and Reliability of the potential Titrimetric method in various complex situations.
