Could you please help me to know a very simple method to measure the amount of Sulfite (SO3) and Sulfate (SO4) ions in the water? (titration preferred)
Have look at this paper:

Dear Mohammad Hossein Karimi Darvanjooghi ,
The following paper uses the basic principle that a Zinc salt renders an insoluble salt with sulphite (and not with sulphate) and a Barium salt renders an insoluble salt with sulphate (and sulphite as well but this ion is already precipitated):
Fogg, D. N., & Wilkinson, N. T. (1952). The determination of sulphur, sulphide, thiosulphate, sulphite and sulphate in commercial calcium chloride. Journal of Applied Chemistry, 2(7), 357-367. See enclosed file
A more advanced potentiometric titration method is described here:
Siskos, P. A., Diamandis, E. P., Gillieron, E., & Colbert, J. C. (1983). Potentiometric titration of sulphate, sulphite and dithionate mixtures, with use of a lead ion-selective electrode. Talanta, 30(12), 980-982.
Best regards.
