1 Scope

GB/T 6324 This section specifies the determination of the majority of liquid organic chemicals in an experimental method for water --- Karl Fisher Hugh coulomb law. This section applies to the determination of the mass fraction of water in the product at 0 to 2.0%. This section does not apply to the main component capable of reacting with the Karl Fischer reagent and sample the water to generate energy and reducing oxidation of iodine or iodide Determination of sample water. In some cases, the sample pretreatment required measures, they have done a specified in the relevant product standard.

3 General Provisions

3.1 Unless otherwise stated in the analysis using only recognized as analytical reagents and GB/T 6682 stipulated three water. 3.2 Karl Fischer reagent contains iodine, an organic base such as pyridine, sulfur dioxide, methanol or other alcohols. Wear chemical protective gloves when operating And other protective equipment, avoid inhalation or direct contact with the reagent vapor skin. 3.3 Sampling and sample pre-treatment in accordance with the appropriate product standard provisions should be avoided external ambient moisture contamination or sample sampling equipment.

4 principle of the method

Present in the sample of any water and Karl Fischer reagent for quantitative reaction, the chemical reaction equation is. H2O I2 SO2 3C5H5N → 2C5H5N · HI SO3 C5H5N · SO3 C5H5N · SO3 CH3OH → C5H5N · HSO4CH3 Karl Fischer coulometric moisture analyzer in a measuring electrode and a pair of electrodes for electrolysis reaction system changes for iodine measurement An anode electrode compartment electromotive force detected drive changes electrolytic electrolysis electrodes, an electrolytic oxidation, respectively, on an anode electrode, a cathode, also ......
