  • ISO 6227-1982 - 中外标准 - - 1982/9 - 现行
    Describes a method based on the potentiometric titration of the chloride ions with standard volumetric silver nitrate solution in an acid medium and in the presence of acetone, using a silver electrode or a chloride or silver ion-selective electrode (measuring electrode) and a calomel or a mercury(I) sulphate electrode (reference electrode). Is a applicable to test solutions having chloride concentrations, expressed in milligrams per litre, of between 1 and 1500.

    All the iron(III) present in the test solution is reduced to iron(II) with ascorbic acid. At a pH between 2 and 9 1,10-phenanthroline is added. the measurement of the absorbance of the orange-red complex formed is carried out at the wavelength of maximum absorption (510 nm). The method is applicable to test solutions from which an aliquot portion can be taken containing between 10 and 500 g of Fe in a volume of not more than 60 m. Details of certain interferences and means by which they can be overcome are given in an annex.
