Description
Titrimetric determination of Sulphite
Titrimetric determination with addition of iodine solution and reverse titration of unused iodine with sodium thiosulphate. Oxidizing and reducing substances interfere.
Sulphite ions are not present in natural unpolluted waters, however they often appear in large quantities in industrial waste waters (e. g. paper mills, dye works).
