Abstract: Methods for estimation of limestone reactivity far absorption of SO₂ from fume gases are described. Eight samples of limestone were tested. Chemical methods are based on the reaction of suspension of limestone powder in water with 0.5 M-H₂SO₃ and 0.5 M-H₂SO₄. It is shown that both procedures give equivalent results. A correlation between the reactivity of limestone and apparent porosity of limestone powder was found. A model describing the rate of the reaction of limestone with aqueous solution of SO₂ is discussed.
