Title Determination of sulfur dioxide by acidimetry in the presence of ammonia
Original title Određivanje sumpor-dioksida acidimetrijskom metodom u prisutnosti amonijaka [in Serbocroatian]

Abstract Description of a method enabling sulfur dioxide concentrations to be corrected when obtained by acidimetric titration in the presence of ammonia. Sulfur dioxide and ammonia can be efficiently collected in the same absorbing solution (0.06% H2O2). If the excess of ammonia or sulfur dioxide is determined by titration and total ammonia by colorimetry, the amount of bound sulfur dioxide can be calculated from the difference. The method has been successfully evaluated with samples of known composition and is suitable for the field.
